MAX7042 Description
The MAX7042 fully integrated, low-power, CMOS superheterodyne RF receiver is designed to receive frequency-shift-keyed (FSK) data at rates up to 66kbps nonreturn-to-zero (NRZ) (33kbps Manchester). The MAX7042 requires only a few external ponents to realize a plete wireless RF receiver at 308, 315, 418, and 433.92MHz. The MAX7042 includes all the active ponents required in a superheterodyne receiver including a...
