FEMTOCLOCK CRYSTAL-TO-3.3V LVPECL CLOCK GENERATOR
Applications Information
Power Supply Filtering Technique
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 ICS843051 provides separate
power supplies to isolate any high switching noise from the outputs
to the internal PLL. VCC and VCCA 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 VCC pin and also shows that VCCA requires that an additional
10
resistor along with a 10F bypass capacitor be connected to the
VCCA pin.

Crystal Input Interface
The ICS843051 has been characterized with 18pF parallel
resonant crystals. The capacitor values, C1 and C2, shown in Figure
2 below were determined using a 26.04167MHz, 18pF parallel
resonant crystal and were chosen to minimize the ppm error. The
optimum C1 and C2 values can be slightly adjusted for different
board layouts.
