YMF752-S Datasheet
YMF752
Preliminary
AC’97 Rev2.1 Audio CODEC with SRC
OVERVIEW
YMF752 is an AC’97 Audio CODEC LSI, which is fully compliant with the industry standard “Audio
CODEC ’97” component specification (Revision 2.1).
YMF752 includes a SRC (Sampling Rate Converter) for supporting variable sampling rate and an AC-Link
serial interface. Therefore, YMF752 is the best audio solution for both laptops and desktop PCs as well as
AMR (Audio Modem Riser) and MDC (Mobile Daughter Card).
YMF752 also supports low power consumption while normal operating and allows for controlling the power
down mode.
