Analog Devices Expands Synthesis, Simulation Capabilities Of PLL Circuit Design Tool
Norwood, MA -- Analog Devices, Inc. (ADI) today released 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 customers 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.
"When we first introduced the ADIsimPLL tool two years ago, it redefined PLL synthesizer design by removing time-consuming iterations from the design process, increasing accuracy and speeding designs to market," said Christian Kermarrec, VP, RF and wireless systems, Analog Devices. "Since its introduction we have received more than 15,000 downloads of ADIsimPLL, and now with the enhancements featured in Version 2.7, design cycles can be cut by up to 80 percent when compared to traditional evaluation methods."
ADIsimPLL Version 2.7 supports simulations of all key non-linear effects that impact PLL performance. It 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 (voltage-controlled oscillator) characterization data ensures accurate simulations, and the library data also has Web-based references. A single mouse click accesses a PLL or VCO device's Web page. Analog Devices 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). Now, users can also simulate systems that employ the new family of ISM-band transmitters/transceivers from ADI, featuring FSK modulation. This allows interactive optimization of the loop filter in such systems and increases design efficiency.
ADIsimPLL allows designers to directly modify derived parameters such as the loop bandwidth, phase margi,n and pole locations, and instantly observe the effects of the changes on performance.
ADIsimPLL Version 2.7 is available now free of charge as a download, allowing designers to run simulations locally.
