The clock and data recovery function is dependent on the receiver’s ability to recover the data from the incoming RF signal. There
exists a technique to test the clock and data recovery function without having to set up the receiver to receive data. This is a test mode
that allows an input data stream (square wave at

the data rate) on the RSSI pin, with the recovered clock data appearing on the
CLKOUT pin and the recovered data appearing on the TX/RX pin, respectively. Once the AMIS-52150 is configured for clock and data
