ApplicationThe CS4361 accepts data at standard audio sample rates including 48, 44.1 and 32 kHz in SSM, 96, 88.2 and 64 kHz in DSM, and 192, 176.4 and 128 kHz in QSM. Audio data is input via the serial data input pin (SDIN). The Left/Right Clock (LRCK) determines which channel is currently being input on SDIN, and the optional Serial Clock (SCLK) clocks audio data into the input data buffer.Pinout

DescriptionThe CS4361 is a complete 6-channel digital-to-analog output system including interpolation, multi-bit D/A conversion, and output analog filtering in a small 20-pin package. The CS4361 supports all major audio data interface formats.
The CS4361 is based on a fourth order, multi-bit, deltasigma modulator with a linear analog low-pass filter. This device also includes auto-speed mode detection using both sample rate and master clock ratio as a method of auto-selecting sampling rates between 2 kHz and 216 kHz.
The CS4361 contains on-chip digital de-emphasis, operates from a single +3.3 V or +5 V power supply with
separate built-in level shifter for the digital interface, and requires minimal support circuitry. These features are ideal for DVD players & recorders, digital televisions, home theater and set top box products, and automotive audio systems.
