Description
The CS4228A codec provides two analog-to-digital and
six digital-to-analog delta-sigma converters, along with
volume controls, in a compact 28-pin SSOP device.
Combined with an IEC958 (SPDIF) receiver (like the
CS8414) and surround sound decoder (such as one of
the CS492x or CS493xx families), it is ideal for use in
DVD player, A/V receiver and car audio systems sup-
porting multiple standards such as Dolby Digital AC-3,
AAC, DTS, Dolby ProLogic, THX, and MPEG.
A flexible serial audio interface allows operation in Left
Justified, Right Justified, I
2
S, or One Line Data modes.
