Date
-Removed “Preliminary” tag on front page.
-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 2.5 V. 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 serious distortion. If there is no
analog CD input, then this pin can be No-Connect. “
Release in IDT format.
Updated part ordering information to longer orderable part number related to previously issued
PCN.
