HCMOS Square Wave
MERCURY
Since 1973
Mercury OC11T is 25.4x25.4 mm (1 inch square) 5 pin solder sealed metal
pacakge with 19.0x19.0 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. 50 ohm load sine wave output is available as OC11E series..
General Specifications ( 10 MHz at+25°C, at specified Vcc and +2.5 V Vcon)
Output Wave Form
HCMOS square wave. Wave form code is “T”
Frequency Range
1.25 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
±0.5 ppm max. at time of shipment; Vcon=+2.5V, at +25°C
Operating Temperature Range
