FEMTOCLOCKSCRYSTAL-TO-
LVCMOS/LVTTL FREQUENCY SYNTHESIZER
APPLICATION INFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise.The ICS840002 provides sepa-
rate power supplies to isolate any high switching
noise from the outputs to the internal PLL. V
DD, VDDA, and VDDO
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 10F and a .01μF bypass
capacitor should be connected to each V
DDA.

CRYSTAL INPUT INTERFACE
The ICS840002 has been characterized with 18pF parallel
resonant crystals. The capacitor values shown in Figure 2
Figure 2. CRYSTAL INPUt INTERFACE
below were determined using a 26.5625MHz, 18pF parallel
resonant crystal and were chosen to minimize the ppm error.
