The ML145170 single-chip phase/frequency detector with serial interface is now available with full support from Lansdale Semiconductor. The frequency synthesizer integrated circuit (IC) can be used with input signals from 5 to 80 MHz or from 25 to 185 MHz, depending on input signal levels, to generate stabilized outputs. Originally designed and built by Motorola/Freescale Semiconductor, it features an easy-to-program architecture. Due to the patented BitGrabber registers, no address/steering bits are required for random access of the three registers. As a result, tuning can be accomplished via a 2-Byte serial transfer to the 16-b N register. The synthesizer IC is available in a choice of dual-in-line-package (DIP) and surface-mount-technology (SMT) packages, including DIP-16, SO16, and TSSOP-16 packages.
