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-P E CL to LV-P ECL: 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.

LV-PECL to LVDS: Restricted for short transmission lengths.

Configuration may require modification depending on LVDS receiver.

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.

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:

Environmental Compliance

Parameter Conditions

Mechanical Shock MIL-STD-883, Method 2002

Mechanical Vibration MIL-STD-883, Method 2007

Solderability MIL-STD-883, Method 2003

Gross and Fine Leak MIL-STD-883, Method 1014

Resistance to Solvents MIL-STD-883, Method 2016

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.
