Product Details

The HMC704 has been designed for the best phase noise and lowest spurious content possible in an integrated synthesizer. Fabricated in a SiGe BiCMOS process, this Fractional-N frequency synthesizer consists of a very low noise digital phase detector, VCO divider, reference divider and a precision controlled charge pump.

Ultra low in-close phase noise and low spurious allows wide loop bandwidths for faster frequency hopping and low micro-phonics. Exact frequency mode with 24-bit fractional modulator provides the ability to generate fractional frequencies with zero frequency error, an important feature for Digital Pre-Distortion systems.

The serial interface offers read back capability and is compatible with a wide variety of protocols.

    (GSM, PCS, DCS, CDMA, WCDMA)
  • Wireless LANs, WiMAX
  • Communications Test Equipment
  • CATV Equipment
  • Automotive

Tools & Simulations

Design Tools

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.

ADIsimFrequency Planner Tool

For those developers dealing with integer boundary spurs from Analog’s PLL synthesizers, the best solution is ADIsimFrequencyPlanner. The frequency planner quickly analyzes the PFD frequency for a user’s output requirements and then optimizes the frequency of each output to identify the highest contributing integer boundary spur performance.

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.
