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 is applied before Vcc.

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.
LV-PECL to LVDS: Restricted for short transmission lengths.
Configuration may require modification depending on LVDS receiver.

Functional Test: Allows standard power supply configuration.
Since AC coupled, the LV-PECL levels cannot be measured.
Production Test: Allows direct DC coupling into 50Ω measurement
equipment. Must bias the power supplys as shown. Similar to Figure 1.

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and
IR reflow simulation. The SO-720 family is capable of meeting the following qualification tests:

Gross and Fine Leak
Resistance to Solvents
Handling Precautions
Although ESD protection circuitry has been designed into the SO-720 proper precautions should be taken when
handling and mounting. VI employs a Human Body model (HBM) and a Man-Man model (MM) for ESD
susceptibility testing and design protection evaluation.

The device is designed to meet the JEDEC standard
for Pb-Free assembly. The temperatures and time
intervals listed are based on the Pb-Free small body
requirements. The SO-720 device is hermetically
sealed so an aqueous wash is not an issue.
