CS42516
110 dB, 192 kHz 6-Ch Codec with S/PDIF Receiver
Features
General Description
Six 24-bit D/A, two 24-bit A/D Converters
110 dB DAC / 114 dB ADC Dynamic Range
-100 dB THD+N
The CS42516 codec provides two analog-to-digital and
six digital-to-analog delta-sigma converters, as well as
an integrated S/PDIF receiver.
The CS42516 integrated S/PDIF receiver supports up
to eight inputs, clock recovery circuitry and format auto-
detection. The internal stereo ADC is capable of inde-
pendent channel gain control for single-ended or
differential analog inputs. All six channels of DAC pro-
vide 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 con-
trols or ADC overflow indicators.
System Sampling Rates up to 192 kHz
S/PDIF Receiver Compatible with EIAJ
CP1201 and IEC-60958
Recovered S/PDIF Clock or System Clock
Selection
8:2 S/PDIF Input MUX
ADC High-Pass Filter for DC Offset Calibration
The CS42516 is ideal for audio systems requiring wide
dynamic range, negligible distortion and low noise, such
as A/V receivers, DVD receivers, digital speaker and
automotive audio systems.
Expandable ADC Channels and One-Line
Mode Support
Digital Output Volume Control with Soft Ramp
Digital +/-15 dB Input Gain Adjust for ADC
Differential Analog Architecture
The CS42516 is available in a 64-pin LQFP package in
both Commercial (-10° to 70° C) and Automotive
(-40° to 85° C) grades. The CDB42518 Customer Dem-
onstration board is also available for device evaluation.
