Pin description

Pin Name I/O type Function
1 OE Input Output enable High: Specified frequency output from OUT pin
Low: Out pin is low (weak pull down), only output driver is disabled.
ST Input Standby High: Specified frequency output from OUT pin
Low: Out pin is low (weak pull down)
Device goes to standby mode. Supply current reduces to the least as I_std.
2 GND Power Ground
3 OUT Output Clock output
4 VCC Power Power supply

To maintain stable operation, provide a 0.1µF by-pass capacitor at a location as near as possible to the power source terminal of the crystal product
(between VCC - GND).
