PBA RF Module
ATM511
5GHz Wireless Audio Transceiver
REV: 01
8 /20
DEC 23,2019
There are two available I2S digital audio data inputs/outputs, each of these can be configured to operate as either
a master or a slave – depending on the application, the I2S ports can operate simultaneously as either inputs or
outputs. When configured as slaves, the I2S inputs/outputs can be independently clocked by up to two external
masters. In addition, MCLK can be output from the module to provide a reference clock source to an external ADC
or DAC. MCLK can also be input to the module to provide a reference clock from an external source.
The hardware for the audio input (transmit) and audio output (receive) versions of the module is identical and
only the firmware loaded onto the module determines its function.
The ATM511 module is powered from +3.3V supply input.
