MAX3804 Evaluation Kit
General Description
The MAX3804 DC-coupled evaluation kit (EV kit) simpli-
fies evaluation of the MAX3804 12.5Gbps settable
equalizer. The EV kit enables full testing of the device
functions including all equalization settings. SMA con-
nectors with 50鈩?controlled-impedance transmission
lines to the MAX3804 are provided for all CML input
and output ports.

Quick Start
Note:
The MAX3804 EV kit is a DC-coupled evaluation
board. Care must be taken to ensure that no
direct short between the supply voltage and sup-
ply ground exists. Use external coupling capaci-
tors on the input and output when AC-coupling is
desired. DC-coupled operation with positive V
CC
supplies normally causes permanent damage to
laboratory test equipment (typical oscilloscope,
BERT). The MAX3804 EV kit must be operated
from a negative V
EE
supply when DC-coupled to
normal laboratory equipment.
1) Connect a -3.3V power supply to TP3 (V
EE
).
Connect the power-supply ground to TP2 (GND)
and J6 (V
CC
). Install shunts in JP2 and JP3, and
remove shunt from JP1.
2) Install shunts across pins 2 and 3 of JPEQ1, JPEQ2,
and JPEQ3 for minimal equalization (0, 0, 0). See
Table 1 for the relationship between nominal path
loss and FR-4 microstrip path length.
3) Apply a differential input signal (400mV
P-P
to
1200mV
P-P
) between SMA connectors J1 and J2
(SDI+ and SDI-).
4) Attach a differential high-speed oscilloscope with a
50鈩?input to SMA connectors J3 and J4 (SDO+ and
SDO-) to observe the output of the equalizer.
