Stresses in excess of these absolute maximum ratings can permanently damage the device. Also, exposure to
these absolute maximum ratings for extended periods can 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, FS, or OD) draws
greater than 100 mA.

LV-PECL to LV-PECL: For short transmission lengths, the power
consumption could be reduced by removing the 100Ω 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.
-1.3V: 5,13
NC or Gnd: 4,6,7,9,11,14
Production Test: Allows direct DC coupling into 50Ω measurement
equipment. Must bias the power supplys as shown. Similar to Figure 1.
