General Description

The MAX1005 is a combined digitizer and reconstruction integrated circuit designed to work in systems that demodulate and modulate communications signals.

It integrates IF undersampling and signal synthesis functions into a single, low-power circuit.

Its analog-todigital converter (ADC) is used to directly sample or undersample a downconverted RF signal, while its digital-to-analog converter (DAC) recreates the IF subcarrier and transmission data.
