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

consumption could be reduced by removing the 100

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.
