Description

Serial Sound Interface

(SSI)

● 4 channels bidirectional serial transfer

● 2 external clock sources available

● Full Duplex communication

● Support of I2S / Monaural / TDM audio formats

● Support of master and slave functions

● Generation of programmable word clock and bit clock

● Multi-channel formats

● Support of 8, 16, 18, 20, 22, 24, and 32-bit data formats

● Support of 32-stage FIFO for transmission and reception

● Support of LR-clock continue function in which the LR-clock signal is not stopped

Pulse Density Modulated (PDM)

Interface

● 3 channels

● Capable of filtering 1-bit digital input data PDM_DATn (n = 0,..,2) and converting them into 20-

bit or 16-bit digital data.

● Support of stereo microphone (L/R sampling by rising/falling clock edge).

● Support of sound activity detector.

● Support of programmable filters: 4th order sinc filter, high-pass filter (for suppression of DC

bias), correction filter (for sinc passband distortion), half-band decimation filter (for aliasing

distortion).

● Internal buffer: Capable of storing voice data during low power mode

SPDIF

● Supports the IEC 60958 standard (stereo and consumer use modes only).

● Supports sampling frequencies of 32 kHz, 44.1 kHz, and 48 kHz.

● Supports audio word sizes of 16 to 24 bits per sample.

● Biphase mark encoding.

● Double buffered data.

● Parity encoded serial data.

● Simultaneous transmit and receive

● Receiver autodetects IEC 61937 compressed mode data
