General Description
The TH7122 is a single chip FSK/FM/ASK transceiver IC.
It is designed to operate in low-power multichannel programmable or single-channel stand-alone, half-duplex data transmission systems.
It can be used for applications in automotive, industrial-scientific-medical (ISM), short range devices (SRD) or similar applications operating in the frequency range of 300 MHz to 930 MHz. In programmable user mode, the transceiver can operate down to 27 MHz by employing an external VCO varactor diode.

Features
* Single chip solution with only a few external components
* Stand-alone fixed-frequency user mode
* Programmable multi-channel user mode
* Low current consumption in active mode and very low standby current
* PLL-stabilized RF VCO (LO) with internal varactor diode
* Lock detect output in programmable user mode
* On-chip AFC for extended input frequency acceptance range
* FSK for digital data or FM for analog signal reception
* FSK/ASK mode selection
* RSSI output for signal strength indication and ASK reception
* ASK detection normal or with peak detector
* Switchable LNA gain for improved dynamic range
* Automatic PA turn-on after PLL lock
* ASK modulation achieved by PA on/off keying
* 3wire bus serial control interface
* EVB comes with a cable to connect to a PC’s LPT port
* EVB programming software is available on Melexis web site

Application Examples
* General bi-directional half duplex digital data RF signaling or analog signal communication
* Tire Pressure Monitoring Systems (TPMS)
* Remote Keyless Entry (RKE)
* Low-power telemetry systems
* Alarm and security systems
* Wireless access control
* Garage door openers
* Networking solutions
* Active RFID tags
* Remote controls
* Home and building automation
