Description

The RF2905 is a monolithic integrated circuit intended for use as a low cost FM transceiver. The device is provided in 7mmx7mm, 48-lead plastic LQFP packaging and is designed to provide a fully functional FM transceiver. The chip is intended for linear (AM, FM) or digital (ASK, FSK, OOK) applications in the North American 915MHz ISM band and European 433MHz and 868MHz ISM bands. The integrated VCO, dual modulus/dual divide (128/129 or 64/65) prescaler, and reference oscillator require only the addition of an external crystal to provide a complete phase-locked oscillator.
