This document serves as a reference for the PCM4222EVM evaluation module. When
used in conjunction with commonly available audio test equipment, the PCM4222EVM
provides a complete environment for evaluating the functionality and performance of
the PCM4222 integrated circuit. Indirectly, the PCM4222EVM serves as an evaluation
platform for the PCM4220 integrated circuit; the PCM4220 is a subset derivative of the
PCM4222 device.
This document includes information regarding absolute operating conditions,
power-supply requirements, and hardware configuration for the evaluation module. The
electrical schematics and bill of materials are also included for reference purposes.
Throughout this document, the acronym EVM and the phrase evaluation module are
synonymous with the PCM4222EVM.
