CDB4272

Overview

The CDB4272 is a dedicated evaluation board for the CS4272 high-performance 24-bit, 192 kHz stereo audio codec. It provides a complete environment for testing the codec's differential analog inputs and outputs, featuring integrated S/PDIF digital audio transceivers for flexible connectivity. The board supports both hardware and software configuration modes to streamline the development of professional audio systems.

Why Choose This Part

The board includes on-board CS8416 and CS8406 S/PDIF chips, allowing for easy digital audio interfacing without extra hardware. It features a proven layout design that demonstrates optimal grounding and decoupling techniques for maintaining the codec's high dynamic range. Support for logic levels from 3.3V to 5.0V ensures compatibility with a wide range of modern microcontrollers and DSPs.

Applications

Getting Started

Connect a +/-18V power supply for the analog stages and a 3.3V to 5.0V source for the logic interface. Use the provided Windows-compatible software to configure the CS4272 internal registers via the parallel port or an external I2C/SPI bridge. External digital audio can be injected via the RCA phono or XLR connectors, or through the direct serial header for DSP interfacing.
