SM5170AV

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.

FEATURES

s Supply voltages

• VDD1 = 0.95 to 1.2 V

(prescaler, counters)

• VDD2 = 2.0 to 3.3 V (charge pump)

s FIN input frequency

• fFIN = 300 MHz (VDD1 = 0.95 V)

• fFIN = 330 MHz (VDD1 = 1.0 V)

s Reference frequency

• fXIN = 25 MHz (VDD1 = 0.95 V)

s 20 to 262140 reference frequency divider ratio

range (with 1/4 prescaler built-in)

s 1056 to 131071 FIN input frequency divider ratio

range

s −10 to 60 °C operating temperature range
