Hi,
I have a question with regards to the input clock received and the master clock used.
If the SRC4392 is set up to use the Master clock running at 22.5792MHz and the incoming data is 16bit 44.1kHz stereo - standard CD data, what is the impact of 30ppm clock differences between the incoming signal (optical) embedded clock and the Master clock of the SRC4392.
As an example - if both clocks source (CD Player) and receiver (DAC) are 30ppm different and both use a 22.5792MHz clock - then every 1 second, 2 x 16bit words extra will bet transmitted than expected by the SRC4392. If the input data rate is 30ppm slower than the Master clock of the SRC4392 - what happens here ?
I know that the SRC4392 has internal buffers - but if the CD Player is 30ppm faster than the SRC4392 - will the SRC4392 drop the 2 x 16bit extra words every second ?.
How does the SRC4392 cope with the different clock rates ? and potential buffer overruns and under-runs ?
Thanks and regards,
Richard.
