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.

Suggested Output Load Configurations (3.3V Operation)

LV-PECL to LV-PECL: For short transmission lengths, the power

consumption could be reduced by removing the 100

Ω 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.
