1 Introduction

The PCM182xEVM/ PCM182xQ1EVM is an evaluation module (EVM) designed to demonstrate the performance and functionality of the PCM182x / PCM182x-Q1 device. The devices covered are PCM1820/PCM1821/PCM1822/PCM1820-Q1/PCM1821-Q1/PCM1822-Q1.The PCM182x/ PCM182x-Q1 is a high-performance audio analog-to-digital converter (ADC) that is configured through logic-level mode selection pins and does not require a digital interface such as I2C or SPI to configure registers. As such, no software is necessary to interface with the EVM. The EVM is powered with a single 5-V supply. Access to the converter output is provided on the audio serial interface in I2S or TDM format.
