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.

FEATURES

■ Up to 90 MHz operating frequency (VDD1 = VDD2 = 0.95 V)

■ Up to 100 MHz operating frequency (VDD1 = VDD2 = 1.00 V)

■ Supply voltages

• VDD1 = VDD2 = 0.95 to 1.5 V (prescaler, counters)

• VDD3 = 2.0 to 3.3 V (charge pump)

■ 40 to 16376 reference frequency divider ratio range (with 1/8 prescaler built-in)

■ 1056 to 262143 operating frequency divider ratio range

■ Power-save function for reduced power dissipation

■ −10 to 60 °C operating temperature range

■ 16-pin VSOP

■ Molybdenum-gate CMOS process
