MLX71122中文资料Multi-channel programmable FSK/FM/ASK receiver - 27 to 930 MHz数据手册Melexis规格书

描述 Description

The MLX71122 is a multi-channel receiver integrated circuit (IC) based on a double-conversion superheterodyne architecture.
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 433 and 868 MHz or for the use in North America or Asia, for example at 315, 447 or 915 MHz.
