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.
