Confidential Draft CS4352 6/18/07 192 kHz Stereo DAC with 2 Vrms Line Out Features Description Multi-bit Delta-Sigma Modulator The CS4352 is a complete stereo digital-to-analog sys- tem including digital interpolation, fifth-order multi-bit 24-Bit Resolution delta-sigma digital-to-analog conversion, digital de-em- Supports Sample Rates up to 192 kHz phasis, analog filtering, and on-chip 2 Vrms line-level 106 dB A-wt Dynamic Range driver. The advantages of this architecture include ideal differential linearity, no distortion mechanisms due to re- -93 dB THD+N sistor matching errors, no linearity drift over time and Integrated Line Driver temperature, high tolerance to clock jitter, and a minimal 2 Vrms Output into 5 k AC Load set of external components. Analog Low-Pass Filter The CS4352 is available in a 20-pin TSSOP package in Stereo Mutes with Auto-Mute Function both Commercial grade (-40C to +85C) and Automo- tive grade (-40C to +105C). The CDB4352 Customer Low Clock-Jitter Sensitivity Demonstration Board is also available for device evalu- Low-Latency Digital Filtering ation and implementation suggestions.
