PCM4104EVM

TEXAS INSTRUMENTS PCM4104EVM Evaluation Board, Digital to Analogue Converter, PCM4104

The provides a convenient platform for evaluating the performance and functionality of the PCM4104 device. A switch on the EVM allows the user to select the audio clock and data source, which is either the audio serial port or the AES3 receiver output. When using the audio serial port, data for the eight audio channels can be input independently. An external 2nd-order Butterworth low-pass active filter circuit filters each PCM4104 analog output. The PCM4104EVM can be configured to operate in either Standalone on software mode. In Standalone mode onboard switches provide direct control of the dedicated input pins. While in the software mode, the PCM4104 can be controlled by buffered inputs controlled by microprocessor, digital signal processor, or another device operating the PCM4104 SPI port.
