CRYSTAL CONTROLLED OSCILLATORS

The Connor-Winfield

OFA5AB1BA is a hermetically

sealed 14 Pin DIP, 5.0V Oven

Stabilized Crystal Oscillator

(OCXO) with a Sinewave

output. The OFA5AB1BA is

designed for applications

requiring low jitter and tight

frequency stability.

PACKAGE CHARACTERISTICS

TABLE 4.0

Package

14 pin DIP, hermetically sealed, welded package.

Notes:

1) Initial calibration @ 25°C.

2) Frequency stability, absolute over th e temperature range of 0 to 70 °C.

3) Frequency stability per 5% change in supply voltage.

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

5) Inclusive of calibration, operating temperature ra nge, supply voltage change, shoc k and

vibration and aging (20 years).

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

frequency, measured after 30 m inutes of continuous operation at a stable 25°C.
