All dimensions are in millimeters.
1 _{Inclusive of initial frequency tolgerance, operating temperature range, 20 years aging, input}
voltage change, load change, shock and vibration.
2 _{For proper operation, a control voltage (Vc) must be applied to pin 1 on VCTCXOs.}
3 _{An internal pullup resistor from pin 9 to pin 10 allows active output if pin 9 is left open.}
Note: The above specifications, having been carefully prepared and checked, is believed to be
accurate at the time of publication; however, no responsibility is assumed by Fox Electronics
for inaccuracies.
Dimensional drawing is for reference to critical specifications defined by size measurements.
Certain non-critical visual attributes, such as side castellations, etc. may vary.
