Typical Networks
XTAL1
The reference clock is based on a classic Colpitts architecture with three external capacitors.
The bias circuitry of the oscillator is optimized to produce a low drive level for the XTAL. This reduces
XTAL aging.
Note:

Any parallel-mode 10.245 MHz crystal can be used. Its load capacitance must be between 10 pF and
20 pF.
