1 / 10 page SM5170AV NIPPON PRECISION CIRCUITS—1 NIPPON PRECISION CIRCUITS INC. 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 s 16-pin VSOP PINOUT (Top view) ORDERING INFORMATION D e vice P a ck ag e SM5170AV 16-pin VSOP 1 9 16 8 XIN XOUT VDD2 DB DO VSS FIN TEST NC OPR LE DATA CLK LD VDD1 NC |
