PCM6480-Q1: PCM6480-Q1 issue

Part Number: PCM6480-Q1

Hi,

According to the datasheet, I can set the GPIO1 as "SDOUT2", so I can use two I2S interfaces.

Now I want to use 4 channels(4 Dmic or 2 Amic+2 Dmic), then I only need to use Slot 0 and Slot 1.

Is the I2S interfaces can only output Slot 0 and Slot 1 In this situation? (do not need Slot 3, Slot 4 .......)

  • Hi Frank,

    The output format of PCM6480-Q1 is extremely flexible. You can have all of the data on a single TDM formatted line, split it into two separate data lines in traditional I2S formatting, or even output it on a single data line in a I2S/TDM hybrid format. As long as you have a sufficient BCLK to FSYNC ratio to support the slots you need then there are many options for formatting.

    Best,

    Zak
