Product Overview

The PCM4222EVM is an evaluation module for evaluating the performance and functionality of the PCM4222 ADC. The PCM4222 is a high performance, two channel analog to digital (A to D) converter. Offering outstanding dynamic performance, the PCM4222 supports 24bit linear PCM, 1bit direct stream digital (DSD), and 6bit modulator data outputs. The supported output formats make the PCM4222 ideal for digital audio recording and processing applications. When used in connection with commonly available audio test equipment, the PCM422EVM provides a complete environment for evaluating the functionality and performance of the PCM4222 integrated circuit. Each analog input is buffered by an input circuit employing the OPA1632 fully differential audio amplifier. These amplifiers are selected for their low noise and distortion, and contain fully differential input to output architecture.
  • Simple configuration using switches and power supply jumpers
  • Two DIT4192 digital audio interface transmitters to provide AES3 encoded data
  • Two onboard crystal oscillators provide support for common audio sampling rates
  • Light emitting diodes (LED) overflow indicators for the left and right audio channels
  • A buffered data port header provides one bit direct stream digital (DSD) output data
  • Buffered modulator output port header provides access to PCM4222 modulator data outputs and clocks
  • Minimum power supply requirements
