Overview

SM5165AV NIPPON PRECISION CIRCUITS INC.
PLL Synthesizer IC OVERVIEW The SM5165AV is a PLL synthesizer IC developed for application in pagers and fabricated using NPC’s Molybdenum-gate CMOS process.
It incorporates independently-controlled reference frequency and operating frequency dividers, and operates from a low-voltage supply to realize low power dissipation.
