After channel selection, the digital output is scaled with a digital PGA, which is controlled with the DGAIN. DACs drive a differential analog signal onto the RXIP, RXIN, RXQP, RXQN pins to interface to standard analog-input baseband IC. SAMSUNG Proprietary-Contents may change without notice 2- 1...
