CS4364/84

The CS4364/84 are pin-compatible 6- and 8-channel digital-to-analog systems. They feature digital de-emphasis, half-dB step-size volume control, ATAPI channel-mixing, selectable fast and slow digital interpolation filters followed by an oversampled, multibit Delta-Sigma modulator which includes mismatch shaping technology that eliminates distortion due to capacitor mismatch. Following this stage is a multielement switched capacitor stage and low-pass filter with single-ended analog outputs.

Both ICs feature a proprietary DSD processor which allows for volume control and a 50 kHz on-chip filtering with an intermediate decimation stage. CS4364/84 also offers an optional path for direct DSD conversion by directly using the multielement switched capacitor array. They accept PCM data at sample rates from 4 kHz to 216 kHz, DSD audio data and deliver excellent sound quality. These features are ideal for multichannel audio systems including SACD players, A/V receivers, digital televisions, mixing consoles, effects processors, sound cards and automotive audio systems.
