SM5168 series

PLL Synthesizer IC

OVERVIEW

The SM5168 series are PLL synthesizer ICs fabricated using NPC’s Molybdenum-gate CMOS process. They

provide several combinations of reference and comparator frequency divider ratios, set in master-slice, making

them ideal for frequency synthesizers in IF stages of mobile communications devices. They also feature a lock

detect signal output (LD).
