The clock applied to the SL RC400 acts as time basis for the coder and decoder of the synchronous system.
Therefore stability of clock frequency is an important factor for proper performance. To obtain highest
performance, clock jitter shall be as small as possible. This is best achieved using the internal oscillator
buffer with the recommended circuitry (see 12).
