Analog Devices, Inc. has introduced a new version of its phase-locked loop (PLL) circuit design and evaluation tool. ADIsimPLL version 2.7 features enhanced synthesis and simulation capabilities, as well as expanded libraries and Web access, further streamlining the RF development process for users of ADI's fractional-N and integrated VCO/PLL products. These products are used in applications such as wireless base stations, LAN, mobile handsets/PDAs, broadband wireless access, industrial and instrumentation and test equipment, satellite, sonar and CATV.

ADIsimPLL version 2.7 supports simulations of all key non-linear effects that affect PLL performance. The tool adds loop filter options that allow designers to optimize the synthesis algorithms and lower the loop filter's contribution to the overall PLL phase noise. An expanded library of VCO characterization data ensures accurate simulations, and the library data also have Web-based references. A single mouse click accesses conveniently to a PLL or VCO device's Web page. ADI's PLL libraries have been updated to reflect the company's latest product offerings (ADF4193 Fractional-N PLL Synthesizer, ADF7020 ISM-Band Transceiver) as well as ADI's integrated VCO/PLL products (ADF4360-x).

ADIsimPLL version 2.7 is available now free of charge as a download, allowing designers to run simulations locally.
