To maintain stable operation, provide a 0.01uF to 0.1uF by-pass capacitor at a location as near as possible to the power source terminal of the crystal product
(between Vcc - GND).
Note.
OE pin (P,PTJ,PTW,PHW,PCW,PCN,PCG)
OE pin = "H" or "open" : Specified frequency output.
OE pin = "L" : Output is high impedance.
ST pin (STW, SHW, SCW,SCG)
ST pin = "H" or "open" : Specified frequency output.
ST pin = "L" : Output is low level
(weak pull - down),oscillation stops.
