operation of the ICS841S02I
resonant crystal. See Table 7 for complete crystal specifications.
For proper operation, a minimum of 10pF capacitance on each
crystal pin is required. The capacitor values shown in Figure 2

As in any high speed analog circuitry, the power supply pins are
vulnerable to random noise. To achieve optimum jitter
performance, power supply isolation is required. The ICS841S02I
provides separate power supplies to isolate any high switching
noise from the outputs to the internal PLL. V
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 V
also shows that V
along with a 10µF bypass capacitor be connected to the V

are typical values for the recommended crystal as show in
Table 7. The specific values may be adjusted to trim the frequency
for the individual board layouts if desired.
The crystal and optional trim capacitors should be located as
close to the
possible to minimize board level parasitics.
