1 Introduction

The PCM6xx0 device family includes the following high-performance, analog-to-digital converters (ADC):

  • PCM6020 is a two-channel ADC
  • PCM6x40: PCM6240 and PCM6340 are quad-channel ADCs
  • PCM6x60: PCM6260 and PCM6360 are six-channel ADCs
  • PCM6480 is a quad-channel ADC with a quad-channel digital pulse density-modulation (PDM) microphone input.

This family of devices features a flexible audio serial interface that allows the device to be configured as either a controller or target. This document describes the modes, input parameters, and register coefficients required to configure the PCM6xx0 devices as an audio bus controller.
