1:1 DIFFERENTIAL-TO-LVDS ZERO DELAY CLOCK GENERATOR
ICS874S02I
General Description
Features
The ICS874S02I is a highly versatile 1:1 Differential-
• One differential LVDS output pair and
one differential feedback output pair
S
IC
to-LVDS Clock Generator and a member of the
HiPerClockS™ family of High Performance Clock
Solutions from IDT. The ICS874S02I has a fully
integrated PLL and can be configured as a zero
HiPerClockS™
• One differential clock input pair
• CLK/nCLK can accept the following differential input levels:
LVPECL, LVDS, LVHSTL, SSTL
delay buffer, multiplier or divider, and has an output frequency
range of 62.5MHz to 1GHz. The reference divider, feedback
divider and output divider are each programmable, thereby
allowing for the following output-to-input frequency ratios: 8:1, 4:1,
2:1, 1:1, 1:2, 1:4, 1:8. The external feedback allows the device to
achieve “zero delay” between the input clock and the output
clocks. The PLL_SEL pin can be used to bypass the PLL for
system test and debug purposes. In bypass mode, the reference
clock is routed around the PLL and into the internal output
dividers.
• Input frequency range: 62.5MHz to 1GHz
• Output frequency range: 62.5MHz to 1GHz
• VCO range: 500MHz - 1GHz
• External feedback for "zero delay" clock regeneration with
configurable frequencies
• Programmable dividers allow for the following output-to-input
frequency ratios: 8:1, 4:1, 2:1, 1:1, 1:2, 1:4, 1:8
• Cycle-to-cycle jitter: 35ps (maximum)
• Static phase offset: 100ps
• Full 3.3V supply mode
• -40°C to 85°C ambient operating temperature
• Available in standard (RoHS 5) package

All control pins have internal pull-ups or pull-downs; additional
resistance is not required but can be added for additional
protection. A 1kΩ resistor can be used.
All unused LVDS output pairs can be either left floating or
terminated with 100Ω across. If they are left floating, there should
be no trace attached.

Power Supply Filtering Technique
As in any high speed analog circuitry, the power supply pins are
vulnerable to random noise. To achieve optimum jitter perform-
ance, power supply isolation is required. The ICS874S02I provides
separate power supplies to isolate any high switching noise from
the outputs to the internal PLL. VDD, VDDA and VDDO should be
individually connected to the power supply plane through vias, and
0.01µF bypass capacitors should be used for each pin. Figure 1
illustrates this for a generic VDD pin and also shows that VDDA
requires that an additional 10Ω resistor along with a 10µF bypass
capacitor be connected to the VDDA pin.

Wiring the Differential Input to Accept Single-Ended Levels
Figure 2 shows how the differential input can be wired to accept
single-ended levels. The reference voltage V_REF = VDD/2 is
generated by the bias resistors R1, R2 and C1. This bias circuit
should be located as close as possible to the input pin. The ratio of
R1 and R2 might need to be adjusted to position the V_REF in the
center of the input voltage swing. For example, if the input clock
swing is only 2.5V and VDD = 3.3V, V_REF should be 1.25V and

Differential Clock Input Interface
The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, and
other differential signals. Both signals must meet the VPP and
VCMR input requirements. Figures 3A to 3E show interface
examples for the HiPerClockS CLK/nCLK input driven by the most
common driver types. The input interfaces suggested here are
examples only. Please consult with the vendor of the driver
component to confirm the driver termination requirements. For
example, in Figure 3A, the input termination applies for IDT
HiPerClockS open emitter LVHSTL drivers. If you are using an
LVHSTL driver from another vendor, use their termination
recommendation.

3.3V LVDS Driver Termination
A general LVDS interface is shown in Figure 4. In a 100Ω
differential transmission line environment, LVDS drivers require a
matched load termination of 100Ω across near the receiver input.
For a multiple LVDS outputs buffer, if only partial outputs are used,
it is recommended to terminate the unused outputs.

1:1 DIFFERENTIAL-TO-LVDS ZERO DELAY CLOCK GENERATOR
The following component footprints are used in this layout
example.
trace delay might be restricted by the available space on the board
and the component location. While routing the traces, the clock
signal traces should be routed first and should be locked prior to
routing other signal traces.
All the resistors and capacitors are size 0603.
• The 100Ω differential output traces should have the same
length.
Power and Grounding
Place the decoupling capacitors as close as possible to the power
pins. If space allows, placement of the decoupling capacitor on the
component side is preferred. This can reduce unwanted
inductance between the decoupling capacitor and the power pin
caused by the via.
• Avoid sharp angles on the clock trace. Sharp angle turns
cause the characteristic impedance to change on the
transmission lines.
• Keep the clock traces on the same layer. Whenever possible,
avoid placing vias on the clock traces. Placement of vias on
the traces can affect the trace characteristic impedance and
hence degrade signal integrity.
Maximize the power and ground pad sizes and number of vias
capacitors. This can reduce the inductance between the power and
ground planes and the component power and ground pins.
• To prevent cross talk, avoid routing other signal traces in
parallel with the clock traces. If running parallel traces is
unavoidable, allow a separation of at least three trace widths
between the differential clock trace and the other signal trace.
The RC filter consisting of R7, C11, and C16 should be placed as
close to the VDDA pin as possible.
Clock Traces and Termination
• Make sure no other signal traces are routed between the
clock trace pair.
Poor signal integrity can degrade the system performance or cause
system failure. In synchronous high-speed digital systems, the
clock signal is less tolerant to poor signal integrity than other
signals. Any ringing on the rising or falling edge or excessive ring
back can cause system failure. The shape of the trace and the
• The series termination resistors should be located as close to
the driver pins as possible.

Power Considerations
This section provides information on power dissipation and junction temperature for the ICS874S02I.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS874S02I is the sum of the core power plus the analog power plus the power dissipated in the load(s).
The following is the power dissipation for VDD = 3.3V + 5ꢀ = 3.465V, which gives worst case results.
•
The maximum current at 85°C is as follows:
IDD_MAX = 93mA
IDDA_MAX = 19mA
IDDO_MAX = 36mA
•
•
Power (core)MAX = VDD_MAX * (IDD_MAX + IDDA_MAX) = 3.465V * (93mA + 19mA) = 388.08mW
Power (outputs)MAX = VDDO_MAX* IDDO_MAX = 3.465V * 36mA = 124.74mW
Total Power_MAX = 388.08mW + 124.74mW = 512.82mW
•
2. Junction Temperature.
Junction temperature, Tj, is the temperature at the junction of the bond wire and bond pad and directly affects the reliability of the device.
The maximum recommended junction temperature for HiPerClockS devices is 125°C.
The equation for Tj is as follows: Tj = θJA * Pd_total + TA
Tj = Junction Temperature
θJA = Junction-to-Ambient Thermal Resistance
Pd_total = Total Device Power Dissipation (example calculation is in section 1 above)
TA = Ambient Temperature
In order to calculate junction temperature, the appropriate junction-to-ambient thermal resistance θJA must be used. Assuming no air flow
and a multi-layer board, the appropriate value is 64.7°C/W per Table 7 below.
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:
85°C + 0.513W * 64.7°C/W = 118.2°C. This is well below the limit of 125°C.
This calculation is only an example. Tj will obviously vary depending on the number of loaded outputs, supply voltage, air flow and the type
of board (single layer or multi-layer).
