1. DESCRIPTION

1.1. Overview

The 92HD005/92HD005D are high fidelity, 4-channel HD Audio CODECs that enable 2.0 Audio with

simultaneous real-time communication such as VoIP, conferencing, voice command and control, etc.

Up to four digital microphones are supported enabling high quality voice input for increased usability

of voice applications.

The 92HD005/92HD005D incorporate IDT's proprietary SD technology to achieve a DAC SNR of

90dB. The higher performance and quality of IDT’s audio solutions brings consumer electronics level

performance to the notebook, desktop and media center PC.

The 92HD005/92HD005D provide stereo, 24-bit, full duplex resolution, supporting sample rates up

to 192 KHz by the DAC and ADC. The 92HD005/92HD005D SPDIF In/Out supports sample rates of

96 KHz, 48 KHz and 44.1 KHz plus SPDIF OUT supports 88.2 KHz and 192 KHz. Additional sample

rates are supported by the driver software.

The 92HD005/92HD005D support all desired four channel configurations, including switchable

Headphone (HP) Out and Universal Jacks™ functionality for jack detection and re-tasking. The

SPDIF interface provides connectivity to consumer electronic equipment like Dolby Digital decoders,

powered speakers and mini-disk drives, or to a home entertainment system. All analog I/O pairs sup-

port LINE_IN, LINE_OUT and MIC. (Port D only supports fixed-function microphone.)

MIC inputs can be programmed with 0/10/20/30/40dB boost. For more advanced configurations, the

92HD005/92HD005D have five General Purpose I/O (GPIO) pins. The 92HD005/92HD005D also

provide single ended CD input for compatibility with DRM solutions and to support legacy OS issues.

The 92HD005/92HD005D integrate two headphone amplifiers which are available on Ports A and D.

The headphone amplifiers are dedicated to these two outputs for increased flexibility, enhanced user

experience, and reduced implementation costs.

The Universal Jack capabilities allow the CODECs to detect when audio devices are connected, and

allow the CODECs to be reconfigured to support these devices regardless of which port they are

connected to. SPDIF input sensing is also supported. The fully parametric IDT SoftEQ can be initi-

ated upon headphone jack insertion and removal for protection of notebook speakers.

The 92HD005/92HD005D operate with a 3.3 V digital supply and either 3.3 V or 5 V analog supply.

They also support 1.5 V and 3.3 V HDA signaling; the correct voltage is selected dynamically based

on the value of the appropriate pin.

The 92HD005/92HD005D are available in a 48-pin LQFP or a 48-pad QFN Environmental (ROHS)

package.

1.3. Detailed Description

1.3.1.

Low-voltage High Definition Audio Link Signaling

The 92HD005/92HD005D are compatible with either 1.5 V or 3.3 V High Definition Audio Link signal-

ing; the voltage selection is performed dynamically based on the input voltage of DVDD_IO. Note

that DVDD_IO is not a logic configuration pin but provides the digital power supply to be used for the

High Definition Audio Link signals.

When in 1.5 V mode, the 92HD005/92HD005D can correctly decode BITCLK, SYNC, RESET# and

SDO because they operate at 1.5 V. Additionally, it will drive SDI_CODEC at 1.5 V. None of the

GPIOs are affected, as they always function at their nominal voltage (DVDD or AVDD).

1.3.2.

Digital Microphone Support

The digital microphone interface permits connection of digital microphones to the

92HD005/92HD005D via the DMIC0, DMIC1, and DMIC_CLK three-pin interface. The DMIC0 and

DMIC1 pins carry either 1 or 2 channels of digital microphone data to the 92HD005/92HD005D. In

the event that a single microphone is used, the data is routed to both ADC channels.

The DMIC_CLK output is programmable from 1.176 MHz to 4.704 MHz in 1.176 MHz increments

and is synchronous to the 24 MHz internal clock. The default frequency is 2.352 MHz.

The 92HD005/92HD005D supports the digital microphone configurations listed in Table 1.

Volume/Digital Microphone/GPIO Selection

For the 92HD005/92HD005D, three functions are available on pins 2 and 3. To determine which

function is actually enabled on these pins, the order of precedence is followed:

1. If the GPIOs are enabled through the Audio Function Group, they override both Volume Control

and Digital Microphones.

2. If the GPIOs are not enabled through the Audio Function Group, then, at reset, the Volume con-

trol is enabled with a weak pull-up.

3. If BIOS or other software application enables either Digital Microphone input through the Config-

uration Default Register, the Volume is disconnected and the pull-ups are disconnected, with the

weak pull-downs enabled.

1.3.4.

VRefOut/GPIO Selection

Two functions are available on pins 30 and 31. To determine which function is enabled on the two

pins, the order of precedence followed is:

1. If the GPIOs are enabled, they override VRefOut-E or VRefOut-F.

2. If the GPIOs are not activated through the Audio Function Group, then, at reset, the VRefOut

pins are enabled.

If using the GPIOs as inputs, incorporate 10 KW external pull-ups or the GPI will not function cor-

rectly.

1.3.5.

1.3.6.

SPDIF Input

SPDIF IN can operate at 44.1 KHz, 48 KHz or 96 KHz, and implements internal Jack Sensing.

A sophisticated digital PLL allows automatic rate detection and accurate data recovery. The ability to

directly accept consumer SPDIF voltage levels eliminates the need for costly external receiver ICs.

Advanced features such as record-slot-select and SPDIF_IN routing to the DAC allow for simulta-

neous record and play.

SPDIF Output

SPDIF Output supports 44.1 KHz, 48 KHz, 88.2 KHz, 96 KHz and 192 KHz sample rates, as defined

in the Intel High Definition Audio Specification, with resolutions up to 24 bits. This insures compatibil-

ity with all consumer audio gear and allows for convenient integration into home theater systems and

media center PCs.

Mono Output

MONO Output is supported on pin 32 and has an independent mute and volume control. The MONO

Output derives input from the output of the summing node after DAC0. The following analog signals

feed the summing amplifier that feeds the MONO Output summing amplifier:

•

DAC0 Output: When enabled, both DAC0 Outputs are summed together.

Analog PC Beep: Sourced from pin 12.

ADC Input: Stereo analog feed into the stereo ADC input.

The combination of the stereo channels from DAC0 are combined into a single analog signal

with a -6dB degradation in signal strength.

Note: MONO Output only works with the IDT Driver.

1.3.8.

Universal Jacks™

The Universal Jacks™ technology allows for the greatest flexibility in board design and implementa-

tion.

Mono Output cannot be reconfigured

Note: 1) On the 92HD005/92HD005D, only one function can be selected on each pin pair at a

time. For example, a pin pair cannot be configured as an input and output at the same time.

Configuration can be changed at any time.

Note: 2) Port D does not provide a microphone bias pin. Therefore only an internal, fixed-function

microphone can be supported.

Note: 3) Headphone capabilities are provided on Ports A and D, however, audio performance

degrades when 2 headphones are enabled.

Note: 4) When the 40dB microphone boost feature is enabled, additional gain increases greater

than 6dB may result in significant audio quality degradation of the microphone audio input. In

particular, when the 40dB microphone boost is active, the SNR, THD+N and DC offset will

significantly degrade regardless of the input signal level.

1.3.8.1.

Jack Detect

SENSE_A pin is used to detect the presence of plugs in ports A, B, C, and D. SENSE_B pin is used

to detect the presence of plugs in ports E and F. Refer to the 92HD005/92HD005D reference design

for port detect circuitry.

Impedance Sense

Impedance Sensing is accomplished by on-chip circuitry that tests the impedance at the pin of the

chip and compares it to internal reference impedance. Table 4 describes the bin information and the

codes that are returned when the Pin Widget Impedance field in the Port Pin Sense widget is read.

Please note that even under the best conditions, there is no method to guarantee 100% impedance

sensing due to variations in external circuitry and impedance overlap of devices that can be plugged

into a jack. The impedance sense table reflects both standard Line Out and Headphone output driv-

ers.

3. Not active if BITCLK is not running.

4. This mode can only be exited with a Bus Reset.

5. VAG is always ramped up and down gradually, except in the case of a sudden power

removal.

The D3-default state is available for HD Audio compliance. The programmable values exposed via

vendor-specific settings are under the IDT Device Driver control for further power reduction.

The default power state for the Audio Function Group after reset is D3-default.

1.3.10. Analog PC-Beep

PC Beep may need to be active on power up, in which case the BIOS is responsible for enabling it

by setting AnalogBeepEn in the AFG AnaCtrl widget. The PC_BEEP input is routed directly to the

MONO_OUT, LINE_OUT and HP_OUT pins of the CODEC. Because the PC_BEEP input drive is

often a full scale digital signal, some resistive attenuation of the PC_BEEP input is recommended to

keep the beep tone within reasonable volume levels. The user should mute this input before using

any other mixer input because the PC Beep input can contribute noise to the lineout during normal

operation.

Analog PC-Beep is not supported during Link Reset.

3.2. Pin Configuration Default Register Settings

The configuration default registers are 32-bit registers required for each pin widget. These registers

are normally used by the CODEC driver to determine the configuration of jacks and devices attached

to the CODEC. When the CODEC is powered on, these registers are loaded with the default values

provided by IDT for typical system usage, and are loaded in a way that is compatible with the

Microsoft Universal Audio Architecture (UAA) driver. The values can be overridden by IDT custom-

ers according to their system configuration. Table 9 shows the Pin Widget Configuration Default set-

tings.

There are two types of responses: Solicited and Unsolicited. Solicited responses are provided as a

direct response to an issued command and will be provided in the frame immediately following the

command. Unsolicited responses are provided by the CODEC independent of any command. Unso-

licited responses are the result of CODEC events such as a jack insertion detection. The formats for

Solicited Responses and Unsolicited Responses are shown in Tables 12 and 13 respectively. The

“Tag” field in bits [31:28] of the Unsolicited Response identify the event.

An internal power supply anti-pop circuit

prevents audible clicks and pops from being

heard when the CODEC is powered on and

off. This function is accomplished by

delaying the charge/discharge of the VREF

capacitor. A value of C_VREF= 1 µF will

cause a turn-on delay of roughly 3 seconds,

which will allow the power supplies to

stabilize before the CODEC outputs are

enabled. The recommended value of

C_VREF= 10 µF will extend the delay to

30 seconds. The CODEC outputs are also

kept stable for the same amount of time at

power-off to allow the system to be

6. DESIGN CONSIDERATIONS

6.1. External Components

The 92HD005/92HD005D requires a minimum number of external components for proper operation.

6.1.1.

Decoupling Capacitor

Decoupling capacitors must be connected between AVDD and AVSS and between DVDD and

DVSS, as close to these pins as possible.

•

Between AVDD (pin 38) and AVSS (pins 26 and 42), use a 1.0 mF capacitor in parallel with a

10 mF capacitor.

Between AVDD (pin 25) and AVSS (pins 26 and 42), use a 0.1 mF capacitor in parallel with a

10 mF capacitor.

Between DVDD (pin 1) and DVSS (pins 4 and 7), use a 1.0 mF capacitor in parallel with a 10 mF

capacitor.

Between DVDD (pin 9) and DVSS (pins 4 and 7), use a 0.1 mF capacitor in parallel with a 10 mF

capacitor.

For optimum device performance, the decoupling capacitors should be mounted on the CODEC side

of the PCB. Avoid the use of vias in the decoupling circuit.

6.1.2.

Other Required Components

The following components are required:

•

Between VREFFILT (pin 27) and AVSS (pins 26 and 42), use a 1.0 mF capacitor in parallel with

a 10 mF capacitor.

•

Each of these pins needs to have an 820 pF capacitor connected to AVSS (pins 26 and 42).

(Recommend using NP0 type capacitor.)

•

ADC0_AFILT_L (pin 28).

ADC1_AFILT_L (pin 29).

ADC0_AFILT_R (pin 30).

ADC1_AFILT_R (pin 31).

•

ADC_VREF (pin 33) must have a 1.0 mF capacitor connected to AVSS (pins 26 and 42). Option-

ally, a 10 mF capacitor may also be connected in parallel, to improve performance.

SENSE_A (pin 13) and SENSE_B (pin 34) must each be connected to AVSS (pins 26 and 42)

with a 1000 pF capacitor located as close to the pins as possible.

SENSE_A (pin 13) and SENSE_B (pin 34) must each be connected to AVDD (pins 25 and 38)

with a 5.11 KW resistor. This resistor MUST be 1% tolerance and should be located as close to

the pins as possible.

•

Either SENSE_A or SENSE_B is connected to each Port through a resistor. This resistor MUST

be 1% or better tolerance. (For resistor details, see Table 3. For details about these connections,

see the latest IDT reference designs.)

For optimum device performance, these components should be mounted on the CODEC side of the

PCB. Minimize the use of vias.

6.2. PCB Layout Recommendations

An optimum layout is one with all components on the same side of the board, minimizing vias

through other signal layers. Other signal traces should be routed away from the

92HD005/92HD005D. This includes signal traces just underneath the device, or on layers adjacent

to the ground plane layer used by the device.

Separate analog and digital grounding is recommended. The analog grounds (AVSS (pins 26 and

42)) and the digital grounds (DVSS (pins 4 and 7)) should be tied together at only one place. This tie

should be under the CODEC.

Capacitive coupling is allowed for EMI considerations. Generally, use 0.1 mF capacitors. Make sure

these are spread out in the layout.

Analog ground (AVSS) should be located on all grounding layers. AVSS should be the same shape

on these layers.

Analog audio signals should not escape the AVSS cut.

Analog non-audio signals should not enter the AVSS cut.

Only audio voltage planes (such as AVDD) should be located on the VCC layer.

Analog voltage should be provided from a filtered source. LDO’s are preferred. Ferrite beads are

acceptable. Whichever is used must support current requirements.

6.2.1.

Vista WLP Compliance Requirements

The following external components are REQUIRED for Vista WLP compliance.

Required series coupling capacitors on analog I/O signal lines:

•

Minimum Premium Desktop Implementations:

•

Line Output = 10 mF, 1206, 10 V, X5R (ceramic) or 3.3 mF aluminum electrolytic (or similar).

Headphone Output = 220 mF aluminum electrolytic (or similar).

Microphone or Line Input = 1 mF, 0603, X5R (ceramic) or better.

Minimum Premium Mobile Implementations:

•

Line Output = 2.2 mF, 1206, 16 V, X5R (ceramic).

Headphone Output = 100 mF D-Case size (or similar). Larger is better, we usually recom-

mend 220 mF.

•

Microphone or Line Input = 1 mF, 0603, X5R (ceramic) or better.
