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).
