Mercury OC22T is 50.8X50.8 mm 7 pin solder sealed metal pacakge with
38.1X38.1 mm pin-to-pin spacing high stability low aging OCXO. SC cut
crystal is standard for OC22 . ±0.4 ppb stability and ±150 ppb total aging
over 10 years make the OC22 ideal for base stations, digital switching,
instrumentation and frequency synthesizers. HCMOS output is available as OC22T series.
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
5.0 MHz ~20.0 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.
