LOW VOLTAGE/LOW SKEW, 1:8 PCI/PCI-X
ZERO DELAY CLOCK GENERATOR
APPLICATION INFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS87608I provides sepa-
rate power supplies to isolate any high switching
noise from the outputs to the internal PLL. V
DD, VDDA, and VDDOX
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 1 illustrates how
a 10
Ω resistor along with a 10µF and a .01μF bypass
capacitor should be connected to each V
DDA.

CRYSTAL INPUT INTERFACE
The ICS87608I has been characterized with 18pF parallel
resonant crystals. The capacitor values, C1 and C2, shown in
Figure 2 below were determined using a 25MHz, 18pF parallel

ppm error. The optimum C1 and C2 values can be slightly ad-
justed for optimum frequency accuracy.
