Analog Devices, Inc. announces the release of ADIsimPLL Version 3.0, a new generation of its phase-locked loop (PLL) circuit design and evaluation tool, as well as two PLL synthesizers delivering desirable performance for the upconversion and downconversion of RF signals in wireless base station equipment. ADIsimPLL Version 3.0 offers nine loop filter topologies, a VCO/reference library editor, enhanced VCO libraries, new analysis features, as well as support for six new devices. On the hardware side, the company introduces the ADF4156 and ADF4002, providing low- and high-frequency PLL solutions for a range of wireless base station equipment. The ADF4156 is a fractional-N PLL synthesizer operating at 6 GHz. The ADF4156 is designed to implement local oscillators in the upconversion and downconversion sections of wireless transceivers and transmitters. For low-frequency requirements, Analog Devices offers the ADF4002. Operating at 350 MHz, the ADF4002 frequency synthesizer can be used to implement clock conditioning, clock generation and IF LO generation in wireless receivers and transmitters.
