Product Number

External dimensions

(Unit: mm)

Metal may be exposed on the top or bottom of this product.
This will not affect any quality, reliability or electrical spec.

OE pin (PDE)
OE pin = "H" or "open" : Specified frequency output.
OE pin = "L" : Output is high impedance.

Footprint (Recommended)

(Unit: mm)

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).
