General Description
The TH71101 FSK/ASK single-conversion superheterodyne receiver IC is designed for applications in the European 433MHz 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 300MHz to 450MHz (e.g. for applications according to FCC part 15 and ARIB STD-T67).

FEATUREs
◾ Single-conversion superhet architecture for low external component count
◾ FSK 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
◾ 32-pin Low profile Quad Flat Package (LQFP)

APPLICATION Examples
◾ General digital data transmission
◾ 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
