Description
The CS4228 codec provides two analog-to-digital and
six digital-to-analog delta-sigma converters, along with
volume controls, in a compact +5/+3.3 V, 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.
