The CS4350 is a complete stereo D/A converter with on-chip Phase-Locked Loop (PLL) based master clock derivation.

The integrated PLL locks to the incoming Left-Right clock signal eliminating the need for external master clock line routing, thus simplifying the design and significantly reducing interference and clock jitter sensitivity. The PLL does not require external loop filter components and also generates a high frequency audio master clock.

The CS4350 supports 24-bit resolution and up to 192 kHz sampling rates with 108dB dynamic range performance. The system includes digital interpolation, 5th order multi-bit delta-sigma modulation, digital de-emphasis, volume control, channel mixing, analog filtering and Cirrus Logic's proprietary PopGuard® (optional) and Automatic sample-rate detection technologies.

The CS4350 supports single ended or differential analog outputs and all standard digital audio interface formats, including both PCM and TDM.

The primary target markets are applications where the audio related system clock is not present, such as set top boxes, digital televisions, DVD players and recorders, A/V receivers; the semi-professional audio markets such as audio interfaces, mixing consoles and musical instruments; and the automotive space such as head units, telematics, satellite radio modules and various in-car entertainment systems.
