Description of Change
7.1
History not included in Datasheet
Removed BIT_CLK as an input option from clocking table, it was incorrectly included in 3-1 version
Added CD_GND elaboration note on connection diagram, pin list and pin out diagrams:
“The CD_GND signal is an AC signal return for the two CD input channels. It is normally biased

at about 2.5V. The name of the pin in the AC’97 specification is CD_GND, and this has confused
many designers. It should not have any DC path to GND. Connecting the CD_GND signal
directly to ground will change the internal bias of the entire CODEC, and cause significant
distortion. If there is no analog CD input, then this pin can be No-Connect.”
