Product Number: ADV7511
We are generating the I2S signals externally and inputting them to the ADV7511, and we would like to fix the sampling frequency at 48 kHz.
When the HDMI source’s sampling frequency is 48 kHz, everything works correctly.
However, when the HDMI source’s sampling frequency is 44.1 kHz, 96 kHz, or 192 kHz, the CTS value of the ADV7511 (registers 0x05–0x07) becomes incorrect.
I suspect that there may be some information contained in the InfoFrame coming from the ADV7611.
In this configuration, since MCLK, SCLK, LRCLK, and DATA are all generated externally, we expected that the ADV7511 could operate with a fixed 48 kHz setting.
Is there any additional configuration required?
