PLL Synthesizer IC
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.
