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 75Ω.

BB set at 5k

Ω 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 imped-

ance of the line being driven. The actual resistor value is

media specific, but typically is between 100 and 120

Ω de-

pending 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.
