DIFFERENTIAL CLOCK INPUT INTERFACE
The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, HCSL
and other differential signals. Both V
SWING and VOH must meet the
V
PP and VCMR input requirements. Figures 4A to 4D show inter-
face 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

As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS8732-01 provides
separate power supplies to isolate any high switching
noise from the outputs to the internal PLL. V
CC, VCCA and VCCO
should be individually connected to the power supply plane
through vias, and bypass capacitors should be used for
each pin. To achieve optimum jitter performance, power
supply isolation is required. Figure 3 illustrates how a 10
Ω
resistor along with a 10
μF and a .01μF bypass capacitor
should be connected to each V
CCA pin.

driver component to confirm the driver termination requirements.
For example in Figure 4A, the input termination applies for ICS
HiPerClockS LVHSTL drivers. If you are using an LVHSTL driver
from another vendor, use their termination recommendation.
