Phase Frequency Detector Integrates 40GHz Prescalers

Microsemi PFD1K 8GHz Phase Frequency Detector IC with Dual 40GHz PrescalersRFMW, Ltd. announces design and sales support for a phase-frequency detector from Microsemi. Incorporating dual, 0.01 to 40GHz, 7-bit programmable, high-speed prescalers for reference and VCO inputs, the PFD1K is ideally suited to phase locked loop applications from DC to 8GHz. The prescalers are 1 to 127, integer dividers that feed the differential input of the phase-frequency detector. Dual charge pumps follow the phase-frequency detector and offer differential outputs. Single Sideband phase noise is -153dBc/Hz @ 10KHz offset. The PFD1K operates with a single positive or negative 3.3V supply, and is packaged in a 40-pin, 6mm x 6mm ceramic leadless surface mount package.
