NOTES:
1. See RECOMMENDED OPERATING RANGE table.
2. For 1.8V LVTTL single-ended operation, the RxS pin is allowed to float or tied to V
3. V
4. V
5. For single-ended operation in differential mode, A/V
6. Voltage required to maintain a logic HIGH, single-ended operation in differential mode.
7. Voltage required to maintain a logic LOW, single-ended operation in differential mode.
8. Typical values are at V
9. The reference clock input is capable of HSTL, eHSTL, LVEPECL, 1.8V or 2.5V LVTTL operation independent of the device output. The correct input interface table should be
10. This value is the worst case minimum V
11. This value is the worst case maximum V
