NJU6398
LVDS-output Quartz Crystal Oscillator IC
!GENERAL DESCRIPTION
The NJU6398 is a quartz crystal oscillator IC with
LVDS output, from 110MHz to 160MHz frequency output,
which consists of an oscillation amplifier, LVDS output,
and 3-state output buffer for each LVDS. The oscillation
amplifier realizes very low oscillation stop current with
NAND circuit. The NJU6398 is suitable for mobile,
optical communications (including WDM system), PC &
Peripherals, telecommunications, LAN/WAN, and
wireless systems

Note2) If the supply voltage(VDD) is less than 7.0V, the input voltage do not over the VDD level.
Note3) Decupling capacitor should be connected between VDD and VSS due to the stabilized operation for the
circuit.
