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).
Metal may be exposed on the top or bottom of this product.
This will not affect any quality, reliability or electrical spec.
Note.
OE pin (PTF,PCE,PDE,PTW,PHW,PCW,PTG,PHG,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.
ST pin (SCE)
ST pin = "H" or "open" : Specified frequency output.
ST pin = "L" : Output is low level ,oscillation stops.
