MAX3803 Evaluation Kit
_______________ General Description
_________________________Features
The MAX3803 dc-coupled evaluation kit (EV kit)
simplifies evaluation of the MAX3803 2.488Gbps to
3.125Gbps equalizer. The EV kit enables full testing of
all the device’s functions. SMA connectors with 50Ω
controlled-impedance transmission lines to the MAX3803
are provided for all CML input and output ports.

Note: The MAX3803 EV kit is a dc-coupled evaluation
board with 50Ω input and output terminations to
VTI and VTO, respectively. Care must be taken
to ensure that no direct short exists between the
supply voltage and supply ground. Normal dc-
coupled operation with all positive supplies
causes permanent damage to laboratory test
equipment because a dc path exists from the
power supply to the ports of the oscilloscope or
BERT. The MAX3803 EV kit must be operated
from a negative VEE supply when DC-coupled
to standard lab equipment. External ac-coupling
capacitors should be used when connecting to
standard lab equipment and when VEE (J11)
and the EV kit’s GND (J2) are at the same
potential.
