CS42518

110 dB, 192 kHz 8-Ch Codec with S/PDIF Receiver

Features

General Description

The CS42518 codec provides two analog-to-digital and eight

digital-to-analog delta-sigma converters, as well as an integrat-

ed S/PDIF receiver, in a 64-pin LQFP package.

z Eight 24-bit D/A, two 24-bit A/D Converters

z 110 dB DAC / 114 dB ADC Dynamic Range

z -100 dB THD+N

The CS42518 integrated S/PDIF receiver supports up to eight

inputs, clock recovery circuitry and format auto-detection. The

internal stereo ADC is capable of independent channel gain

control for single-ended or differential analog inputs. All eight

channels of DAC provide digital volume control and differential

analog outputs. The general purpose outputs may be driven

high or low, or mapped to a variety of DAC mute controls or

ADC overflow indicators.

z System Sampling Rates up to 192 kHz

z S/PDIF Receiver Compatible with EIAJ CP1201

and IEC-60958

z Recovered S/PDIF Clock or System Clock

Selection

z 8:2 S/PDIF Input MUX

z ADC High-pass Filter for DC Offset Calibration

The CS42518 is ideal for audio systems requiring wide dynam-

ic range, negligible distortion and low noise, such as A/V

receivers, DVD receivers, digital speaker and automotive audio

systems.

z Expandable ADC Channels and One-line Mode

Support

z Digital Output Volume Control with Soft Ramp

z Digital +/-15dB Input Gain Adjust for ADC

z Differential Analog Architecture
