Product Details

The HMC703 fractional synthesizer is built upon the high performance PLL platform also contained in the HMC704 and Hittite’s latest generation of PLL+VCO products. This platform has the best phase-noise and spurious performance in the industry - enabling higher order modulation schemes while minimizing blocker effects in high performance radios.

In addition, the HMC703 offers frequency sweep and modulation features, external triggering, double-buffering, exact frequency control, phase modulation and more - while maintaining pin compatibility for the main functions with the HMC700.

Tools & Simulations

Design Tools


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.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
