Description

The TRF4903 single-chip solution is an integrated circuit intended for use as a low-cost multiband FSK or OOK transmitter to establish a frequency-programmable, half-duplex, bidirectional RF link. The multichannel transmitter is intended for digital (FSK, OOK) modulated applications in the North American and European 315-MHz, 433-MHz, 868-MHz, and 915-MHz ISM bands. The single-chip operates down to 2.2 V and is designed for low power consumption. The synthesizer has a typical channel spacing of better than 200 kHz and features a fully-integrated VCO. Only the PLL loop filter is external to the device.

Two fully-programmable operation modes, Mode0 and Mode1, allow extremely fast switching between two preprogrammed settings (for example, TX_frequency_0/TX_frequency_1; …) without reprogramming the device.
