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.
Suggested Output Load Configurations
LV-PECL to LV-PECL:
For short transmission lengths, the
power
consumption could be reduced by removing the 100
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.
