The TH71221ELQ-BAA-000-TU is a single chip FSK/FM/ASK Transceiver IC with operating frequency of 300 to 930 MHz, available in surface mount QFN-32 package.

It is designed to operate in low-power multichannel programmable or single-channel stand-alone, half-duplex data transmission systems.

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
  • 3wire bus serial control interface
  • FSK/ASK mode selection
  • FSK for digital data or FM for analog signal reception
  • RSSI output for signal strength indication and ASK reception
  • Peak detector for ASK detection
  • Switchable LNA gain for improved dynamic range
  • Automatic PA turn-on after PLL lock
  • ASK modulation achieved by PA on/off keying
  • 32-pin Quad Flat Lead Package (QFN)

Applications:

  • 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
