Single-Ended Operation

For single-ended operation of the cable driver or equal-

izer, connect the unused input to ground through a

series combination of a capacitor (of equal value to

other AC-coupling capacitors) and a 50

Ω resistor. Note

that the MAX3800 is specified for differential operation.

Layout Considerations

The MAX3800’s performance can be significantly

affected by circuit-board layout and design. Use good

high-frequency design techniques, including minimiz-

ing ground inductance and using fixed-impedance

transmission lines for the high-frequency data signals.
