The ADF7012 is a low power ASK/FSK/GFSK UHF transmitter designed for use in Short Range Devices (SRD’s). The output power, output channels, deviation frequency and modulation type are programmable by using four 32-bit registers. The fractional-N and VCO with external inductor enable the user to select any frequency in the 50MHz to 1GHz 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 narrowband operation.

There are five different modulation schemes selectable: Binary or Gaussian On-Off Keying (OOK), Binary or Gaussian Frequency Shift Keying (FSK) and Amplitude Shift Keying (ASK). The compensation register allows the output to be moved in < 1ppm steps to allow indirect compensation for frequency error in the crystal reference. Control of the registers is via a simple 3-wire interface. In power-down the part has a typical quiescent current of <0.1μA.

The model number is a specific version of a generic that can be purchased or sampled.

Status indicates the current lifecycle of the product. This can be one of 4 stages:

• Pre-Release: The model has not been released to general production, but samples may be available.
• Production: The model is currently being produced, and generally available for purchase and sampling.
• Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
• Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).

The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
