MAX3805 Evaluation Kit
_______________ General Description
The MAX3805 DC-coupled evaluation kit (EV kit)
simplifies evaluation of the MAX3805 10.7Gbps adaptive
equalizer. The EV kit enables full testing of device
functions. SMA connectors with 50Ω controlled-
impedance transmission lines to the MAX3805 are
provided for all CML input and output ports.

________________________ Quick Start
Note:
The MAX3805 EV kit is a DC-coupled evaluation
board. Use external coupling capacitors on the
input and output when AC-coupling is desired.
DC-coupled operation with positive VCC supplies
can cause permanent damage to laboratory test
equipment (oscilloscope, BERT). The MAX3805
EV kit must be operated from a negative VEE
supply when DC-coupled to normal laboratory
equipment.
1) Connect a –3.3V power supply to VEE. Connect the
power supply ground to GND and VCC. Remove
shunt on JP1; install shunts on JP2 and JP3.
2) Connect TP9 to TP10.
3) Apply a differential 9.953Gbps input signal
(400mVP-P to 1200mVP-P) between SMA connectors
J1 and J2, (SDI+ and SDI-)
4) Attach a differential high-speed oscilloscope with a
50Ω input to SMA connectors J4 and J3 (SDO+ and
SDO-) to observe the output of the equalizer.
