Phase Detector / PLL Frequency Synthesizer

Manufactured by:

Product Details

The ADF4002 frequency synthesizer is used to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. It consists of a low-noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider and programmable N divider. The 14-bit reference counter (R counter), allows selectable REFIN frequencies at the PFD input.

A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). In addition, by programming R and N to 1, the device can be used as a standalone PFD and charge pump.

The ADF4002-EP supports defense and aerospace applications (AQEC standard).

Product Details

The Evaluation board for the ADF4002 contains a SDP connection and software allowing the ADF4002 to be controlled from a SDP board.

This evaluation board requires an SDP Controller board for connection to the PC. The SDP controller board connects to the PC via USB 2.0. The evaluation board will connect to the SDP controller board. The evaluation board cannot be connected directly to the PC. The evaluation software running on the PC will communicate through the SDP Controller board, to the evaluation board. The SDP Controller board is a separate list item in the ordering guide below (EVAL-SDP-CS1Z). If you have not previously purchased an SDP Controller board, please do so to ensure a full evaluation setup.
