General Description
The MLX71122 is a multi-channel RF receiver IC based on a double-conversion super-heterodyne architec-
ture. It is designed to receive FSK and ASK modulated RF signals either in 8 predefined frequency channels
or frequency programmable via a 3-wire serial programming interface (SPI).
The IC is designed for a variety of applications, for example in the European bands at 433MHz and 868MHz
or for the use in North America or Asia, e.g. at 315MHz, 447MHz or 915MHz.
