8.2.1 TRF1305x1 as ADC Driver in a Zero-IF Receiver

TRF1305B1 TRF1305x1 as ADC Driver in a Zero-IF Receiver Figure 8-6 TRF1305x1 as ADC Driver in a Zero-IF Receiver

Consider a zero-IF (direct down conversion) application with an IQ demodulator interfaced to a pair of ADCs. In this case, the TRF1305x1 is used as an interface amplifier between the demodulator and the ADCs. The dc common-mode of the demodulator output and ADC input are different. The TRF1305x1 dc couples the demodulator to ADC without degrading the signal integrity of the signal chain.
