To maintain stable operation, provide a
0.01uF to 0.1uF by-pass capacitor at a loca-
tion as near as possible to the power source
terminal of the crystal product (between VCC -
GND).
Note.
OE Pin (PT, PH, PC)
OE Pin = "H" or "open": Specified frequency output.
OE Pin = "L": Output is high impedance.
ST
Pin (ST, SH, SC)
ST
Pin = "H" or "open": Specified frequency output.
ST
Pin = "L": Output is low level (weak pull - down), oscillation
stops.
