Description

The TRF5901 single-chip solution is a low cost FSK transceiver to establish a frequency-agile, half-duplex, bidirectional RF link. The device is available in a 48-lead TQFP package and is designed to provide a fully functional multichannel FM transceiver. The single-chip transceiver operates down to 3 V and is expressly designed for low power consumption. The synthesizer of TRF5901 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 of TRF5901 can be used to adjust the TX/RX frequency and allows the use of inexpensive reference crystals.

Two fully-programmable operation modes, Mode0 and Mode1, allow fast switching between two preprogrammed settings (e.g., TX(RX)_frequency_0, RX(TX)_frequency_1) without reprogramming the TRF5901. Each functional block of the transceiver can be specifically enabled or disabled via the serial interface.
