CS42428
114 dB, 192-kHz 8-Ch CODEC with PLL

Eight 24-bit D/A, two 24-bit A/D Converters 114 dB DAC / 114 dB ADC Dynamic Range -100 dB THD+N 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 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 Supports Logic Levels between V and 5 V

The CS42428 provides two analog-to-digital and eight digital-to-analog delta-sigma converters, as well as an integrated PLL.

The CS42428 integrated PLL provides a low-jitter system clock. 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.

The CS42428 is ideal for audio systems requiring wide dynamic range, negligible distortion and low noise, such as A/V receivers, DVD receivers, and digital speakers.
The CS42428 is available in a 64-pin LQFP package in Commercial -10° to +70° C grades. The CDB42428 Customer Demonstration board is also available for device evaluation. Refer to “Ordering Information” on page
