192 kHz Stereo, 109 dB D/A Converter with Integrated PLL

The CS4350 stereo audio digital/analog converter (DAC) features excellent dynamic range, out-of-band noise performance and on-chip phase-locked-loop (PLL) based main clock with 24-bit conversion and up to 216 kHz sampling rates with 109 dB dynamic range performance, making the IC ideal for applications where an audio-related system clock is not present. By integrating the PLL, the CS4350 eliminates the need for external main clock routing across the circuit board by locking to the incoming left-right clock signal, as opposed to the video clock or other high-speed clock sources, thus significantly reducing interference and clock-jitter sensitivity.
