NJU6343 Datasheet | New Japan Radio

DESCRIPTION The NJU6343 is a single chip C-MOS IC for VCXO that consists of an oscillation amplifier and 3-state output buffer. The NJU6343 integrates all ponents used in VCXO module, and there is no need for pleting VCXO module to prepare any external ponents except a quartz crystal. It can vary its output frequency by controlling voltage at VC terminal. The oscillation amplifier is realized very low stand-by current using NAND circuit. The 3-state output buffer is C-MOS patible. s FEATURES q Operating Voltage 2.7 to 3.6V q Maximum Oscillation Frequency 50MHz(T.B.D.) q Frequency Pulling Range ±100ppm q Low Operating Current q High Fan-out IOH/IOL= T.B.D @3.0V q Oscillation Stop and Output Stand-by Function q3-State Output Buffer q A Variable Capacitor on-chip q Package Outline Chip q C-MOS Technology s COORDINATES No 1 Pad Name X Y s PACKAGE OUTLINE NJU6343C s PAD LOCATION 2 3 4 CONT XT XT VSS FOUT VC VDD Starting Point:Chip Center Unit[um] Chip Size:1.6x1.6mm Thin-Chip Thickness:260±20um Pad Size:90x90um s BLOCK DIAGRAM Rf Cg Cd - STATE BUFFER FOUT CONT 2002/03/11 ( 1 / 4 ) ..
