The clock applied to the SL RC400 acts as time basis for the coder and decoder of the synchronous system.
Therefore stability of clock the frequency is an important factor for proper performance. To obtain highest
performance, clock jitter has to be as small as possible. This is best achieved by using the internal oscillator
buffer with the recommended circuitry. If an external clock source is used, the clock signal has to be applied
to pin OSCIN. In this case special care for clock duty cycle and clock jitter is needed and the clock quality
has to be verified. It needs to be in accordance with the specifications in chapter 19.5.3.
Remark: It is recommend not to use an external clock source.
