TRF6900A General Description

The TRF6900A 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 available in a 48-lead TQFP package and is designed to provide a fully-functional multichannel FM transceiver. The chip is intended for linear (FM) or digital (FSK) modulated applications in the new 868-MHz European band and the North American 915-MHz ISM band. 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.

Two fully-programmable operation modes, Mode0 and Mode1, allow extremely fast switching between two preprogrammed settings (e.g., receive(RX)/transmit(TX); TX_frequency_0/TX_frequency_1; RX_frequency_0/RX_frequency_1;.) without reprogramming the device. Each functional block of the transceiver can be specifically enabled or disabled via the serial interface.

† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated onditions for extended periods may affect device reliability. NOTE 1: All GND and VCC terminals must be connected to either ground or supply, respectively, even if the function lock is not used.
