The ADF4153A is a fractional-N frequency synthesizer that implements local oscillators in the upconversion and downconversion sections of wireless receivers and transmitters. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. A sigma-delta (Σ-Δ) based fractional interpolator allows programmable fractional-N division. The INT, FRAC, and MOD registers define an overall N divider (N = (INT + (FRAC/MOD))). In addition, the 4-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 a voltage controlled oscillator (VCO).
A simple 3-wire interface controls all on-chip registers. The device operates with a power supply ranging from 2.7 V to 3.3 V and can be powered down when not in use.

Evaluation Kits (1)
The ADF4153A evaluation board is designed to allow the user to evaluate the performance of the ADF4153A frequency synthesizer for phase-locked loops (PLLs). The board contains the ADF4153A synthesizer, an edge mounted SMA connector for the RF output signal, power supply connectors, a temperature compensated reference oscillator (TCXO) of 25 MHz frequency, and an SDP connector. There is also a loop filter (50 kHz) and a VCO (Mini-Circuits ROS-1800+) on 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.
Tools & Simulations
ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
