CS4329 20-Bit, Stereo D/A Converter for Digital Audio Features l 20-Bit Conversion l 115 dB Signal-to-Noise-Ratio (EIAJ) l Complete Stereo DAC System - 128X Interpolation Filter - Delta-Sigma DAC - Analog Post Filter l 106 dB Dynamic Range l Low Clock Jitter Sensitivity l Filtered Line-Level Outputs - Linear Phase Filtering - Zero Phase Error Between Channels l Adjustable System Sampling Rates - including 32 kHz, 44.1 kHz & 48 kHz l Digital De-emphasis for 32 kHz, 44.1 kHz, & 48 kHz l Pin-compatible with the CS4390 I Description The CS4329 is a complete stereo digital-to-analog output system. In addition to the traditional D/A function, the CS4329 includes a digital interpolation filter followed by an 128X oversampled delta-sigma modulator. The modulator output controls the reference voltage input to an ultra-linear analog low-pass filter. This architecture allows for infinite adjustment of sample rate between 1 and 50 kHz while maintaining linear phase response simply by changing the master clock frequency. The CS4329 also includes an extremely flexible serial port utilizing mode select pins to support multiple interface formats. The master clock can be either 256, 384, or 512 times the input sample rate, supporting various audio environments.
