Optical and Coaxial sample rates
Posted: Thu Feb 13, 2020 4:47 pm
Hi,
Hopefully basic questions to answer! Using the xCore-200 as a reference design we're trying to ascertain what are the highest sample rates we can use over optical and coaxial outputs. Our design has only optical and coaxial outputs.
1) Can these two outputs handle all the data rates that the I2S channels can i.e 44.1 KHz right through to 384 KHz ( and higher if possible )?
2) Can the optical and coaxial interfaces pass DSD or is this only possible using the I2S outputs?
Update: A DAC like the Hugo2 claims to handle 192Khz optically and 786KHz ( if split into 2x 384Khz streams ) over coax. Does'nt answer DSD though..
Any additional information regarding optical / SPDIF would be appreciated.
Thanks.
