TRF6900 TI Single Chip RF Transceiver by Texas Instruments
The TRF6900 single-chip solution is an integrated circuit intended for use as a low cost FSK transceiver to establish a frequency-agile, half-duplex, bidirectional RF link. The device is designed to provide a fully-functional multichannel FM transceiver. The single chip transceiver operates down to 2.2 V and is expressly designed for low power consumption.
The synthesizer has a typical channel spacing of approximately 230 Hz to allow narrow-band as well as wide-band application. Due to the narrow channel spacing of the direct digital synthesizer (DDS), the DDS can be used to adjust the TX/RX frequency and allows the use of inexpensive reference crystals.
