Figure 7 shows an AC-coupled, twisted pair cable

application. It implements a center tap capacitance

termination used in conjunction with two 50

Ω resistors to

filter common mode noise. R

of DC bias to each input.

PECL or LVPECL drivers may be interfaced to the

CLC001 as shown in

Figure 8. The voltage divider

network will reduce the PECL output to the proper levels.

For LVPECL, the 100

Ω series resistors should be

removed, since the common mode range inputs of the

CLC001 are wide enough to accept LVPECL levels

directly.

No

external

DC

biasing

is

required

for

PECL/LVPECL connections.
