New Japan Radio NJU6343
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.| Part No. | NJU6343 |
