DESCRIPTION
5
The Connor-Winfield
EGOV3S3 is a hermetically
sealed 14 Pin DIP, 3.3V
Oven Controlled Voltage
Controlled Crystal Oscillator
(OCVCXO) with an
HCMOS/TTL compatible
output. The EGOV3S3 is
designed for higher stability
Stratum 3 applications
requiring low jitter and tight
frequency stability.

ORDERING INFORMATION
Initial calibration @ 25°C, Vc=1.48
Frequency vs. temperature stability
At the time of shipment after48 hours of operation.
Inclusive of calibration, operating temperature range, supply voltage change, load change, shock
and vibration, 20 years aging, Vc=1.48.
5) Measured @ 25°C, within 5 minutes, the unit will be within +/-0.1ppm of its reference frequency,
measured after 30 minutes of co ntinuous operation at a stable 25°C
