SM5956A

6-channel Asynchronous Sample Rate Converter

OVERVIEW

The SM5956A is a digital audio signal, asynchronous sample rate converter LSI. It reads 6-channel 16/20/24-

bit word length input data, and 16/20/24-bit word length output data. It also features a built-in digital deempha-

sis ﬁlter, direct muting and digital audio interface output.

• Input data passed directly to the outputs

^ꢀDigital audio interface output

• DIA input data undergoes sample rate conver-

sion 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)

• Slave mode: Data is output at a rate dictated by

an externally input signal

• Master mode: Sample rate is generated internally

from the output-system clock, and

supplied as an output
