Note:
Please indicate that you are using the MAX3822 EV kit
when contacting these component suppliers.
Quick Start
1) Set the channel-select (CS) pin to enable channel
1 by removing the shunt from J9.
2) Set the threshold level to mid-range by adjusting
threshold control potentiometers R7 and R8 for
650鈩?measured between VTH and ground.
3) Enable the
LOP
and
LOP1
indicators by placing
shunts across the LED side of J22 and J18.
4) Ensure shunts on J23 and J24 are in place.
5) Connect ground and a +3.3V supply to the proper
terminals on the EV kit.
6) Connect the inputs of channel 1 to a 50鈩?source
using 50鈩?SMA cables. Set the source to produce
a differential 50mVp-p 2.5Gbps signal.
7) Connect the outputs of channel 1 to a 50鈩?oscillo-
scope with 50鈩?SMA cables.
8) Power up the EV kit.
9) Check that the amplified and limited input pattern
is present on the output.
