MICRF302YML-TR [Microchip]

The MICRF302 is a parallel encoder that prepares data for transmission across an RF link. It encodes data from four input pins (with internal pull-up resistors and deglitching circuitry) into baseband packets and outputs encoded data serially for direct connection to QwikRadio® transmitters. Features include built-in CRC for reliability, on-chip clock generation requiring no external components, stable operation over -40°C to +85°C temperature range, and wide 1.8V to 3.6V supply voltage range. The device uses Manchester encoding and transmits packets in groups of four for robust communication.
