Hello,
When PCLK switches, there will be momentary loss of lock between serializer and deserializer while the deserializer locks to the new frequency which will interrupt any data traffic in forward channel direction. It is not recommended to use internal oscillator from 925 when transporting video and audio data.
Regards,
Liam
