FEMTOCLOCKS CRYSTAL-TO-LVPECL 350MHZ FREQUENCY MARGINING SYNTHESIZER
PRELIMINARY
APPLICATION INFORMATION
CRYSTAL INPUT INTERFACE
The ICS843207-350 has been character ized with 18pF
parallel resonant crystals. The capacitor values shown in
FIGURE 2. CRYSTAL INPUt INTERFACE
Figure 2 below were determined using a 14MHz, 18pF parallel
resonant crystal and were chosen to minimize the ppm error.
As in any high speed analog circuitry, the power supply pins are
vulnerable to random noise. To achieve optimum jitter perfor-
mance, power supply isolation is required. The ICS843207-350
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 0.01F bypass capacitors should be used
for each pin. Figure 1 illustrates this for a generic V
CC pin and
also shows that V
CCA requires that an additional 10Ω resistor
along with a 10F bypass capacitor be connected to the V
CCA
pin.
