Part Number: DS90UB949-Q1

When bit 6 of register 0x55 is set, which I2S pins on the DS90UB949-Q1 will be used to output the I2S audio?

Thanks,

Hi Mark,

The pins referred to in the description are the deserializer's I2S pins. Depending on how many channels you are using, I2S_DA - I2S_DD will be used along with I2S_CLK and I2S_WC. Do you know how many channels of audio you will be using? I2S_DA will default to the first two channels continuing to channels 7 and 8 assigned on I2S_DD.

Regards,

Jack

Correction: HDMI audio will be output on the serializer's I2S data pins.

Thanks for your help and clarifying the I2S is on pins 33 through 38.
