The Tx and -Rx lines are used for audio transmission, whilst the bit clock (BCLK) and +Rx lines are used for audio transmission, while the bit clock (BCLK) and left/right clock (LRC) synchronise the link. I2S is flexible in that either the controller or CODEC can drive (master) the BCLK and LRC clock lines. Bit clock usually varies depending on the sample rate and the master system clock @@ -49,9 +49,9 @@ PCM PCM is another 4 wire interface, very similar to I2S, which can support a more flexible protocol.

PCM also supports Time Division Multiplexing (TDM) in that several devices can use the bus simultaneously (this is sometimes referred to as network mode). |
