CS4328

CS4328 18-Bit, Stereo D/A Converter for Digital Audio Features General Description Complete Stereo DAC System 8× Interpolation Filter 64× Delta-Sigma DAC Analog Post Filter Adjustable System Sampling Rates including 32kHz, 44.1kHz & 48kHz 120 dB Signal-to-Noise Ratio Low Clock Jitter Sensitivity Completely Filtered Line-Level Outputs Linear Phase Filtering Zero Phase Error Between Channels No External Components Needed Flexible Serial Interface for Either 16 or 18 bit Input Data The CS4328 is a complete stereo digital-to-analog output system. In addition to the traditional D/A function, the CS4328 includes an 8× digital interpolation filter followed by a 64× 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 kHz and 50 kHz while maintaining linear phase response simply by changing the master clock frequency. The CS4328 also includes an extremely flexible serial port utilizing two select pins to support four different interface modes. The master clock can be either 256 or 384 times the input word rate, supporting various audio environments.
