Electrical Quick Start
1) Attach matched 50鈩?SMA cables from a 50鈩?oscillo-
scope to OUT+ and OUT-. Set the oscilloscope to
20mV/div and 200ps/div. A single-ended evaluation
is acceptable; however, the cable not terminated
into the scope should be terminated with a 50鈩?load
at the end of the cable.
2) Ensure that there is a shunt across the VCCS pins.
(Remove shunt for 5.0V operation.)
3) Attach ground to either side of the GND 2-pin
header and +3.3V (or +5.0V) to either side of the
VCCD 2-pin header.
4) Connect a 50鈩?cable between the output of a 50鈩?/div>
source and the input of the EV kit. Set the source to
produce a 2.0Vp-p, 2.5Gbps 1-0 pattern.
5) Adjust R9 and R6 to produce a DC current of 1mA
(1mA = 2.0Vp-p / 1k鈩?/ 2) through R7. This can be
verified by checking for a 1V drop across R7.
6) Verify that the input pattern is present at the output.
