Table Notes:
1. See Standard Frequencies and Ordering Information
2. Parameters are tested with production test circuit
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. Output levels are standard 100K PECL compatible and measured from 20% to 80% of a full output swing (Fig 1).
6. Not tested in production, guaranteed by design, verified at qualification.
7. Integrated across 12 kHz to 20 MHz, or 50 KHz to 80 MHz per GR-253-CORE Issue3. LVPECL Output
8. Tested with Vc = 0.3V to 3V for 3.3V supply, Vc = 0.5V to 4.5 V for 5V supply, Vc = 0.5V to 11.5V for 12V supply
9. Maximum frequency occurs at room temperature

Table Notes:
1. By setting Output Disable pin high, the RF output is disabled and pin 4 is held high, pin 5 is held low.
The threshold for Output Disable is 2.3V above pin 3. Output disable pin can be left floating for normal operation
