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 OS) draws >100 mA.

Functional Test: Allows use of standard power supply biasing
configuration. Pull down resistors are used for LV-PECL outputs
and are removed for with LVDS outputs. Since the LVDS outputs
are AC coupled, the output DC levels cannot be measured.
Production Test: DC levels shown for Vee, OSelect,
& Vc are for devices configured for 3.3V operation.
LV-PECL outputs are DC coupled to 50 test
Vee
equipment. LVDS outputs are connected to a digital volt meter, then AC
coupled to the test equipment. The digitial volt meter allows for Mid Level &
Swing measurements.

LV-PECL to LV-PECL: For short transmission lengths, the pull
down resistor values shown provide reasonable power
consumption and waveform performance.
LVDS to LVDS: The 100 resistor should be removed if this load is
provided internally within the LVDS receiver.
