SM5956A Description
SM5956A 6-channel Asynchronous Sample Rate Converter OVERVIEW The SM5956A is a digital audio signal, asynchronous sample rate converter LSI. It reads 6-channel 16/20/24bit word length input data, and 16/20/24-bit word length output data.
SM5956A Key Features
- 0.45 to 4.41 (SCKSLN = L, 512fso operation)
- 0.225 to 4.41 (SCKSLN = H, 768fso operation) -1 : fsi = input sample rate fso = output sample rate Asynchronous input ti
- Input system clock: 1fsi (LRCI)
- Output-system clock: 512fso/768fso (input on SCK) Deemphasis filter function
- IIR filter structure
- 44.1kHz, 48kHz, 32kHz input sample rate fsi patible Direct mute function Through mode
- Input data passed directly to the outputs Digital audio interface output
- DIA input data undergoes sample rate conversion and is output biphase mark encoded Output data clocks (LRCO, BCKO)
- LRCO rate: 1fso
- BCKO rate: 64fso (SCKSLN = L, 512fso operation) 48fso (SCKSLN = H, 768fso operation)
