ADF7012:  Multichannel ISM Band FSK/GFSK/OOK/GOOK/ASK Transmitter

The ADF7012 is a low power FSK/GFSK/OOK/GOOK/ASK UHF transmitter designed for short-range devices (SRDs). The output power, output channels, deviation frequency, and mod-ulation type are programmable by using four, 32-bit registers.

The fractional-N PLL and VCO with external inductor enable the user to select any frequency in the 75 MHz to 1 GHz band. The fast lock times of the fractional-N PLL make the ADF7012 suitable in fast frequency hopping systems. The fine frequency deviations available and PLL phase noise performance facilitates narrow-band operation.

There are five selectable modulation schemes: binary frequency shift keying (FSK), Gaussian frequency shift keying (GFSK), binary on-off keying (OOK), Gaussian on-off keying (GOOK), and amplitude shift keying (ASK). In the compensation register, the output can be moved in <1 ppm steps so that indirect com-pensation for frequency error in the crystal reference can be made.

A simple 3-wire interface controls the registers. In power-down, the part has a typical quiescent current of <0.1 μA.
