Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation
is not implied at these or any other conditions in excess of conditions represented in the operational sections of
this datasheet. Exposure to absolute maximum ratings for extended periods may adversely affect device
reliability. Permanent damage is also possible if OD or Vc is applied before Vcc.

LV-PECL to LV-PECL:
For short transmission lengths, the power
consumption could be reduced by removing the 100
resistor and
doubling the value of the pull down resistors.
Functional Test:
Allows standard power supply configuration.
Since AC coupled, the LV-PECL levels cannot be measured.
LV-PECL to LVDS:
Restricted for short transmission lengths.
Configuration may require modification depending on LVDS receiver.
