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.
