ADSP21469 SPDIF Rx and Tx latency

Hi all,

 

I can't find any information on the signal delay that the SPDIF receiver and transmitter introduce.

I assume that the transmitter does not generate signal latency at all, however the receiver should.

 

So, let's assume the following:

DSP 1 generates a master clock, outputs a signal via ADCs and passes this signal via SPDIF transmitter to DSP2

DSP2 uses the recovered clocks and outputs the received signal via ADC.

Currently, I measure a delay of 3.5 samples at 48 kHz between these 2 analog signals.

But there should be any official information about this, shouldn't it?

 

Best regards,

 

Rainer
