CS42518/28

110/114 dB, 192 kHz, 2-in, 8-out Multi-Channel CODECs with S/PDIF Receiver

Overview

Description

The CS42518/28 CODEC family provides two analog-to-digital (A/D) and eight digital-to-analog (D/A) Delta-Sigma converters, as well as an integrated S/PDIF receiver.

The CS42518/28 family's integrated S/PDIF receiver supports up to eight inputs, clock recovery circuitry and format autodetection. The internal stereo A/D converter is capable of independent channel gain control for single-ended or differential analog inputs. All eight channels of D/A converter provide digital volume control and differential analog outputs.

The CS42518 and CS42528 are ideal for audio systems requiring wide dynamic range, negligible distortion and low noise, such as audio/video receivers, DVD receivers, digital speakers and automotive audio systems.
