6 SoC controllers and portable audio CODECs today, namely AC97, I2S and PCM.
15 The bit clock (BCLK) is always driven by the CODEC (usually 12.288MHz) and the
27 Rx lines are used for audio transmission, while the bit clock (BCLK) and
28 left/right clock (LRC) synchronise the link. I2S is flexible in that either the
29 controller or CODEC can drive (master) the BCLK and LRC clock lines. Bit clock
30 usually varies depending on the sample rate and the master system clock
35 I2S has several different operating modes:-

50 PCM is another 4 wire interface, very similar to I2S, which can support a more
51 flexible protocol. It has bit clock (BCLK) and sync (SYNC) lines that are used
53 receive the audio data. Bit clock usually varies depending on sample rate
54 while sync runs at the sample rate. PCM also supports Time Division
56 is sometimes referred to as network mode).
58 Common PCM operating modes:-
60 Mode A
63 Mode B
