1 / 11 page SM5166AV NIPPON PRECISION CIRCUITS—1 NIPPON PRECISION CIRCUITS INC. 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 •fFIN = 100 MHz (VDD1 = 1.00 V) •fFIN = 90 MHz (VDD1 = 0.95 V) s Reference frequency •fXIN = 25 MHz (VDD1 = 0.95 V, External Input) •fXIN = 16 MHz* (VDD1 = 0.95 V, Internal oscillaton) NOTE) * : NPC’s recommended frequency. Confirm with crystal supplier. s Unlock signal output pin s Output circuit for passive filter connection s −10 to 60 °C operating temperature range s Standby function for low current consumption s Boost-up signal output for fast locking s Supply voltages •VDD1 = 0.95 to 1.5 V (prescaler, counters) •VDD2 = 2.0 to 3.3 V (charge pump) s 40 to 65528 reference frequency divider ratio range (with 1/8 prescaler built-in) set by serial input data s 1056 to 65535 operating frequency divider ratio range set by serial input data s 16-pin VSOP s Molybdenum-gate CMOS process PINOUT(TOP VIEW) PACKAGE DIMENSIONS Unit: mm 16-pin VSOP 1 9 16 8 XIN XOUT VDD2 DB DO VSS FIN TEST NC OPR LE DATA CLK LD VDD1 NC 5.1 0.2 0.65 0.22 + 0.10 - 0.05 0.15 + 0.10 - 0.05 010 0.5 0.2 |
