Stresses in excess of the absolute maximum ratings can permanently damage the device. Also, exposure to

these absolute maximum ratings for extended periods may adversely affect device reliability. Functional

operation is not implied at these or any other conditions in excess of those represented in the operational

sections of this datasheet. Permanent damage is also possible if any device input (Vc or FS) draws greater

than 100mA.

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

onsumption could be reduced by removing the 100

resistor and

ubling the value of the pull down resistors.

unctional Test: Allows standard power supply configuration.

ince 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.
