NJU6395 Series
QUARTZ CRYSTAL OSCILLATOR
s
GENERAL DESCRIPTION
s
PAKAGE OUTLINE
The NJU6395 series is up to 125MHz low-voltage C-MOS
quartz crystal oscillator, the NJU6395A is up to 110MHz and the
NJU6395B is up to 125MHz.
The NJU6395 series consists of an oscillation amplifier,
internal capacitors (Cg, Cd), feedback resistance (Rf), and
3-state output buffer.
The output is 8mA at 3V and 12mA at 5V operation, which can
drive C-MOS load.

Note2) If the supply voltage(V
DD
) is less than 7.0V, the input voltage must not over the V
DD
level though 7.0V is
limit specified.
Note3) Decupling capacitor should be connected between V
DD
and V
SS
due to the stabilized operation for the
circuit.
Note4) The power dissipation is EMP-8 package without board.
