SM5170AV

PLL Synthesizer IC

NIPPON PRECISION CIRCUITS INC.

OVERVIEW

The SM5170AV is a PLL synthesizer IC developed

for application in pagers. It incorporates indepen-

dently-controlled reference frequency and FIN input

frequency dividers, and operates from a low-voltage

supply to realize low power dissipation. It features a

charge pump that operates at 3 V, making possible a

wide range of VCO designs.

FEATURES
