EVB71112-915-FM-C Datasheet PDF - Melexis Microelectronic Systems

General Description
The TH71112 FSK/FM/ASK double-conversion superheterodyne receiver IC is designed for applications in the European 868 MHz industrial-scientific-medical (ISM) band, according to the EN 300 220 telecommunications standard. It can also be used for any other system with carrier frequencies ranging from 750 MHz to 990 MHz (e.g. for applications to FCC part 15).

FEATUREs
❐ Double-conversion superhet architecture for low high degree of image rejection
❐ FSK for digital data and FM reception for analog signal transmission
❐ FSK/FM demodulation with phase-coincidence demodulator
❐ Low current consumption in active mode and very low standby current
❐ Switchable LNA gain for improved dynamic range
❐ RSSI allows signal strength indication and ASK detection

APPLICATION Examples
❐ Tire Pressure Monitoring Systems (TPMS)
❐ Remote Keyless Entry (RKE)
❐ Wireless access control
❐ Alarm and security systems
❐ Garage door openers
❐ Remote Controls
❐  Home and building automation
❐ Low-power telemetry systems
