Si5317
5.1. Crystal/Reference Clock Selection
An external low-jitter clock or a low-cost crystal is used as part of a fixed-frequency oscillator within the DSPLL.
This external clock is required for the device to perform jitter attenuation. Silicon Laboratories recommends using a
high-quality crystal.
In VCO freeze, the DSPLL remains locked to this external clock. Any changes in the frequency of this clock when
the DSPLL is in VCO freeze will be tracked by the output of the device. Note that crystals can have temperature
sensitivities. Table 13 shows the recommended crystals.
