NJU6343
50MHz VCXO IC
Product Specification
sGENERAL 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 components used in VCXO
module, and there is no need for completing VCXO module to
prepare any external components 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 compatible.
