The TH7122 is a single chip FSK/FM/ASK transceiver IC. It is designed to operate in low-power multi-channel programmable or single-channel stand-alone, half-duplex data tran*ission 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 300MHz to 930MHz. In programmable user mode, the transceiver can operate down to 27MHz by employing an external VCO varactor diode.

• 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 option for extended input frequency acceptance range
• 3wire bus serial control interface
• FSK/ASK modulation selection
• FSK for di*al data and FM for *og signal reception
• RSSI allows 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 Low profile Quad Flat Package (LQFP)
