1. See Standard Frequencies and Ordering Information (Pg 7).

2. Parameters are tested with production test circuit below (Fig 1).

3. Parameters are tested at ambient temperature with test limits guard-banded for specified operating temperature.

4. Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310.

5. Measured from 20% to 80% of a full output swing (Fig 2).

6. Not tested in production, guaranteed by design, verified at qualification.

7. Integrated across stated bandwidth per GR-253-CORE Issue3.

8. Aging Rate for 10 years (Aging is not part of overall frequency stability budget unless specified at time of order)

9. Broadband Period Jitter measured using Lecroy Wavemaster 8600A 6 GHz Oscilloscope, 250K samples taken.

Test Circuit Notes:

1) To Permit 50

Ω Measurement of Outputs, all DC Inputs are Biased Down 1.3V.

2) All Voltage Sources Contain Bypass Capacitors to Minimize Supply Noise.

3) 50

Ω Terminations are Within Test Equipment.
