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 master 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 master 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.

Features

  • Automatic sample-rate detection
  • Low-latency digital filtering
  • Integrated PLL locks to incoming left-right clock - no MCLK required
  • Supports PCM and TDM audio formats
  • Single-ended or differential analog output architecture
