Preliminary Product Brief

CH7315 HDMI Transmitter

FEATURES

GENERAL DESCRIPTION

The CH7315 HDMI transmitter is mixed-signal video

interface chip that transmits uncompressed, copy-

protected video and audio data over a secure link from

PCs to external television, HDTVs, DVD recorders and

A/V receivers using HDMI standard.

•

Supports High-Definition Multimedia Interface

(HDMI) version 1.1 and 1.2

High-speed SDVO^*(1G~2Gbps) AC-coupled serial

differential inputs

Supports Intel® High Definition Audio (HD Audio)

version 1.0

The CH7315 also complies with Intel SDVO (Serial

Digital Video Output} PC interface specification. The

CH7315 HDMI transmitter receives video data through

the SDVO bus, and it receive audio data from via an Intel

HD (High Definition) Audio bus. CH7315 combines

video and audio data, converting it into a single HDMI

compliant bit stream for transmission to external CE

(consumer electronics) devices. The CH7315 device

contains HDCP cryptographic functions and HDCP keys.

•

Support 44.1kHz, 48kHz and 32kHz SPDIF input

Supports switched DVI/HDMI encoding two outputs

port A and B one at the time

Provides High-Bandwidth Digital Content Protection

(HDCP) version 1.1 over HDMI

Support HDMI repeater, a maximum depth of two

with maximum number of two leaves (non-repeating

receivers)

•

Supports HDMI video formats

(480i/576i/240p/480p/288p/576p/720p/1080i/1080p)

specified in EIA/CEA-861C, DVI and VGA outputs.

Supports DVI video formats

(Up to 1600x1200 graphics resolution, refer to Table

4 for more information)

Support video pixel rate range from 25M to165M

pixels per second

Support fixed 24MHz clock input for audio data

synchronization

The CH7315 accepts SDVO serial input speeds of 1Gbps

to 2Gbps and transmits video output at 25Mpps (pixels

per second) to 165Mpps – pixel rates that support all

HDTV display modes from 480I to 1080i/1080p.

The CH7315 device accepts RGB signals of 256-level (0-

255) or 220-level (16-235) over three pairs of serial

differential data ports, then performs the color space

conversion and outputs 256-level (0-255) or 220-level

(16-235) RGB, 4:2:2 YCbCr or 4:4:4 YCbCr data.

•

HDMI video low jitter PLL

The CH7315 device also supports up to 8-channel audio

output at 192 KHz. audio data. Available audio

bandwidth depends on the pixel clock frequency, the

video format timing, and whether or not content

protection re-synchronization is needed.

HDMI hot plug detection

Configuration through Intel® OpCodes^*

Windows XP and Vista support (including MCE and

64-bit variations)

•

Offered in a 64-pin LQFP package

Audio, video and auxiliary data are transmitted across the

three HDMI data channels. The video pixel clock is

transmitted on the HDMI clock channel. In order to

transmit audio and auxiliary data across the HDMI

channels, HDMI uses a packet structure and a special

error reduction coding.

The CH7315 features dual output ports with dedicated

DDC pins so that two external CE devices can be

connected simultaneously and can be selected one at a

time via firmware control. This eliminates the need to

manually switch connectors as consumers swap the active

receiving device from one connector to another. This

feature allows easy implementation of a second HDMI

output via the docking station of a notebook PC.
