Since 1973
Mercury OC31E is 36.2x27.2 mm 5 pin solder sealed metal pacakge
with 25.4x17.8 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 OC31T series.
OC30E series: Same package size as OC31E but with different pin configurations.
General Specifications ( 10 MHz at+25°C, at specified Vcc and +2.5 V Vcon)
Output Wave Form
Sine wave. Wave form code is “E”
Frequency Range
10 MHz ~100.0 MHz
Type of Crystal Cut Used
AT-cut. Use “A” for crystal code or SC-cut: use “S” for crystal code.
SC has better performance but higher cost. See technical note TN-031.
Supply Voltage (Vcc)
+5.0 V D.C ±5% (voltage code is “5”); +12.0 V D.C ±5% (voltage code is “12”)
Initial Calibration Tolerance
