DS90UB953-Q1: i2S Support and FPGA re-sampling

Part Number: DS90UB953-Q1


I have a DS90UB953TRHBRQ1 Serializer moving MIPI data down to a DS90UB954TRGZRQ1.  I need to pass an single channel I2S signal down three of the IO ports.  I will be moving a single channel of 48Khz sampled data along with the Sclk and LRclk.

Will the ‘953 support this?

My thought is that I have 48khz audio which means my SCLK and 24 bits of audio data are moving at just over 3Mhz.  The video path is moving way above that....  I read where the latency of forward channel GPIO inputs (moving from 953 to 954) was on the order of 130ns.  This is roughly 7.6Mhz...  So, If I can move the resulting ‘954 GPIO outputs to a FPGA that can resample at 140Mhz I think I'm fine...

Can you comment on this also?
