The AMIS-52100 single-chip wireless transceiver is the latest member of the line of low data rate ASTRIC (Application Specific Transmit and Receive IC) product family. Aimed at sub-500 MHz band wireless applications that require clock and data recovery, it is suitable for implantable medical devices. The transceiver uses ASK (amplitude shift keying) modulation technology to include clock and data recovery circuitry. The digital base-band circuit post processes a demodulated binary signal to produce an optimally sampled data bit stream and clock signal that is synchronized with the incoming data, removing jitter concerns and maximizing demodulated data integrity. Other features include a quick start oscillator with 15 msec turn-on time that allows the on-board receiver to quickly power up to check for the presence of a signal in its Sniff Mode technology. Sniff Mode is register programmable to optimize power conservation and system performance.
