Device Operation (Continued)

Figure 5 shows the CLC001 with an AC-coupled, single

ended input connection. The 82.5

Ω resister in parallel

with 825

Ω gives the equivalent termination resistance of

Ω.R

BB 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

120

Ω 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.
