Picked up a few NDK 50MHz crystal oscillators with a part number of 1633D Seems like ndk no longer makes them and no datasheet on there website either.

its a surface mount type and has 4 leads...and I believe the pinout is:Pin# Function 1 OE 2 GND 3 OUT 4 VDD
Is Vdd = 3.3V or 5V? anyone have a datasheet on this oscillator P/N 1633D by NDK.
TIA
