OCXO (Oven Controlled Crystal Oscillators) +5.0 V; +12 V
OC40E Series 50 ohm Load Sine Wave
MERCURY
Since 1973
Mercury OC40E is 38.8x38.8 mm 4 pin solder sealed metal pacakge
with 25.4x25.4 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 OC40T series.
General Specifications ( 10 MHz at+25°C, at specified Vcc and +2.5 V Vcon)
Output Wave Form
Frequency Range
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.
