TRI=1 & MS = 0 (Slave mode)
I2S_DOUT is hi-z (I2S_SCLK and I2S_LRCLK are inputs)
TRI=1 & MS = 1(Master mode)
I2S_DOUT, I2S_SCLK, and I2S_LRCLK are hi-z
SCLK rate
See table below
Sample Rate
000 = 44.1KHz
001 = 88.2KHz
010= Reserved
011 = Reserved
100 = 48KHz
101 = 96KHz
110 = 192KHz
111 = Reserved
SCLK is always 64Fs (48KHz based rates have jitter)
SCLK adjusts for sample rate. 44.1KHz based rates
are 64Fs and 48KHz based rates are 84Fs
High jitter (<5nS)
High jitter (<5nS)
