CRYSTAL CONTROLLED OSCILLATORS

The Connor-Winfield

OVA5AB1AA is a hermetically

sealed 14 Pin DIP, 5.0V

Voltage Controlled Oven

Stabilized Crystal Oscillator

(OCVCXO) with a HCMOS /

TTL compatible output. The

OVA5AB1AA is designed for

a higher stability Stratum 3

application requiring low jitter

and tight frequency stability.

PACKAG E CHARACTERISTICS

TABLE 5.0

Package

14 pin DIP, hermetically sealed, grounded case, welded package

Notes:

1) Initial calibration @ 25°C, Vc=2.18V.

2) Frequency stability, 0 to 70°C, peak to peak.

3) Frequency stability per 5% change in s upply voltage.

4) At the time of shipment after 48 hours of operation.

5) Inclusive of operating temperature range, supp ly voltage change, load change, s hock and

vibration, 20 years aging, Vc=2.18V, initial calibration.

6) Measured @ 25°C, within 5 minutes, the unit will be within +/-0.1ppm of its reference

frequency, measured after 30 minut es of continuous operation at a stab le 25°C

7) Referenced to Fo @ 25°C, Positive Transfer Characteristic.
