+5.0 V OC18E Series 50 ohm Load Sine Wave

OCXO (Oven Controlled Crystal Oscillators)
+5.0 V
OC18E Series
50 ohm Load Sine Wave
MERCURY
Since 1973
Mercury OC18E5 is 20.3x20.3 mm 5 pin solder sealed metal pacakge
with 15.2x15.2 mm pin-to-pin spacing high stability low aging OCXO.
Besides standard AT cut crystal, users can also choose SC cut crystal
for better performance. HCMOS square wave output is available as OC18T5 series.
General Specifications ( 10 MHz at+25°C, at +5.0 V Vcc and +2.5 V Vcon)
Sine wave. Wave form code is “E”
10 MHz ~100.0 MHz
AT-cut. Use “A” for crystal code or SC-cut: use “S” for crystal code.
Type of Crystal Cut Used
SC has better performance but higher cost. See technical note TN-031.
