EVAL-ADF7012DBZ4 Datasheet PDF - Analog Devices

GENERAL DESCRIPTION
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.
