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 guardbanded 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 50 kHz to 80 MHz, per GR-253-CORE Issue3.
8. Tested with Vc = 0.3V to 3.0V.

Test Circuit Notes:
1) To Permit 50Ω Measurement of Outputs, all DC Inputs are Biased Down 1.3V.
2) All Voltage Sources Contain Bypass Capacitors to Minimize Supply Noise.
3) 50Ω Terminations are Within Test Equipment.
