CS42416
110 dB, 192 kHz 6-Ch Codec with PLL
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 CS42416 codec provides two analog-to-digital and
six digital-to-analog delta-sigma converters, as well as
an integrated PLL.
The CS42416 integrated PLL provides a low-jitter sys-
tem clock. The internal stereo ADC is capable of
independent 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
! Integrated Low-Jitter PLL for Increased System
Jitter Tolerance
! PLL Clock or System Clock Selection
! 7 Configurable General-Purpose Outputs
! ADC High-Pass Filter for DC Offset Calibration
The CS42416 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 CS42416 is available in a 64-pin LQFP package in
both Commercial (-10° to +70° C) and Automotive
(-40° to +85° C) grades. The CDB42428 Customer
Demonstration board is also available for device evalu-
ation. Refer to “Ordering Information” on page 71.
! Supports Logic Levels between 1.8 V and 5 V
