CC430F5137: Very big jitter in the output synchronous clock when the radio module is in synchronous mode

Part Number:CC430F5137

Hello,

We use CC430F5137 in our devices and we tested the RF examples in slac525b.zip. The purpose is CC430F5137 to be in synchronous mode to receive RF messages from old devices with the following RF parameters: carrier frequency 433.92MHz, baud rate 19.2kbaud, modulation OOK, receiver band width 58kHz. We tested the asynchronous and synchronous modes. In synchronous mode we saw that the output synchronous clock is with very big jitter 19.2kbaud +/-400Hz. Can you tell us why? We expected to see very stable synchronous clock.

By the way, can you tell us is there any synchronization of this synchronous clock with the input data after the demodulator?

Thank you in advance for your answers.

Best regards.
