SC9822P
MP3 DECODER WITH ESP FUNCTION AND CD INTERFACE
DESCRIPTION
SC9822P is a sing-chip Mp3 decoder with electronic shockproof
function. It can be used in CD player, DISC-MAN and such systems
which need MP3 decoder. And this chip provides smaller package,
lower power dissipation and higher cost performance ratio.
FEATURES
* Provide ECC and EDC functions for CD-ROM data error
correcting.
* ISO/IEC 11172-3 L3 L2 L1 decode
LQFP-64-10x10-0.5
* ISO/IEC 13818-3 L3 L2 L1 decode
* Support all MP3 bit rates and free formats under SO/IEC
11172-3 L3 L2 L1 specifications.
* Support all MP3 bit rates and free formats under SO/IEC
13818-3 L3 L2 L1 specifications.
* Support 48K/44.1K/32K MP3 standard sampling rate,
24K/22.05K/16K and 12K/11.025/8K low sampling rate
* Support single/double/stereo/union stereo
