Tools & Simulations

ADIsimPLL™

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.

Open Tool

ADIsimRF

ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.

Accompanying software allows complete control of synthesizer functions from a PC

Product Details

The EV-ADF4108EB1Z evaluation board allows the user to evaluate the performance of the ADF4108 frequency synthesizer for phase-locked loops (PLLs). The board contains the ADF4108 synthesizer, an SMA connector for the reference input, the power supplies, a USB interface, and the RF outputs. There is also an active loop filter and a VCO on board. The user has the option of using an alternate loop filter and VCO by connecting the board to the following SMA connectors: VTUNE and CPOUT. The evaluation kit contains software that is compatible with Windows^® XP and more recent versions to allow easy programming of the synthesizer.

The USB interface allows software programming of the ADF4108 device. A USB cable is included in the evaluation board kit to allow software programmability.
