SM5849BF  
Asynchronous Sample Rate Converter  
OVERVIEW  
The SM5849BF is a digital audio signal, asynchronous sample rate converter LSI. It supports 16/20/24-bit  
word length input data, 16/20/24-bit word length output data, 2kHz to 100kHz input sample rate range, and  
4kHz to 200kHz output sample rate range. It also features a built-in digital deemphasis filter and digital attenu-  
ator.
