SM5166AV
PLL Synthesizer IC
OVERVIEW
The SM5166AV 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.
It features a charge pump that operates at 3 V,
making possible a wide range of VCO designs.
FEATURES
s Operating frequency
• f_FIN = 100 MHz (V_DD1 = 1.00 V)
• f_FIN = 90 MHz (V_DD1 = 0.95 V)
s Reference frequency
• f_XIN = 25 MHz
(V_DD1 = 0.95 V, External Input)
• f_XIN = 16 MHz*
(V_DD1 = 0.95 V, Internal oscillaton)
NOTE) * : NPC’s recommended frequency.
Confirm with crystal supplier.
