19-1291; Rev 0; 9/97 IF Undersampler _______________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. The MAX1005’s ADC is ideal for undersampling applications, due to the analog input amplifier’s wide (15MHz) bandwidth. The DAC has very low glitch energy, which minimizes the transmission of unwanted spurious signals. An on-chip reference provides for low-noise ADC and D [ ... ]
