Micrel MICRF220
The MICRF220 is a 300MHz to 450MHz superheterodyne, image-reject, RF receiver with automatic gain control, ASK/OOK demodulator, analog RSSI output, and integrated squelch features. It only requires a crystal and a minimum number of external components to implement. The MICRF220 is ideal for low-cost, lowpower, RKE, TPMS, and remote actuation applications.- Min Voltage : 3V

GENERAL DESCRIPTION
The MICRF220 achieves −110dBm sensitivity at a bit rate of 1kbps with 0.1% BER. Four demodulator filter bandwidths are selectable in binary steps from 1625Hz to 13kHz at 433.92MHz, allowing the device to support bit rates up to 20kbps. The device operates from a supply voltage of 3.0V to 3.6V, and typically consumes 4.3mA of supply current at 315MHz and 6.0mA at 433.92MHz. A shutdown mode reduces supply current to 0.1μA typical. The squelch feature decreases the activity on the data output pin until valid bits are detected while maintaining
