Figure 5

shows the CLC001 with an AC-coupled, single

ended input connection. The 82.5Ω resister in parallel

with 825Ω gives the equivalent termination resistance of

75Ω.R

set at 5kΩ provides 1.25V of DC bias to the

input.

A typical DC-coupled, twisted pair cable connection is

shown in

Figure 6

. The CLC001 is driven differentially.

The line is terminated with a termination resistor equal to

the impedance of the line being driven. The actual resistor

value is media specific, but typically is between 100 and

120Ω depending upon the cable. This resistor should be

located close to the CLC001 inputs pins to minimize the

resulting stub length between the resistor and device

pads.
