Multiple Protocol Contactless Reader IC

CL RC632

Confidential

12 OSCILLATOR CIRCUITRY

The clock applied to the CL RC632 acts as time basis for the coder and decoder of the synchronous system.

Therefore stability of the clock 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 22.5.3.

Remark: We do not recommend to use an external clock source.
