INPUT TIMING
† _{Bit 1 = MSB = sign bit and is clocked in first on PCM IN or clocked out first on PCM OUT. Bit 8 = LSB = least significant bit and is clocked in}
last on PCM IN or is clocked out last on PCM OUT.
NOTE A: Inputs are driven from 0.45 V to 2.4 V. Time intervals are referenced to 2 V if the high level is indicated and 0.8 V if the low level is
indicated.
