CS4364/84

24-bit, 6- and 8-Channel D/A Converters with DSD Support, Low-Latency Digital Filtering, TDM Interface and Single-ended Output Architecture

Overview

Description

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. It 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.
