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.
The MAX1005 is an 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. The device features a differential-input, 5-bit ADC for directly sampling or undersampling downconverted RF signals and a differential-output, 7-bit DAC for recreating the IF subcarrier and transmission data.
The MAX1005 operates from a single power supply or separate analog and digital supplies with independent voltages ranging from +2.7V to +5.5V. It offers three operating modes: transmit (DAC active), receive (ADC active), and shutdown. The device is available in a 16-pin QSOP package for operation over commercial and extended temperature ranges.
