Operation
INPUT INTERFACING
The CLC006 has high impedance, emitter-follower buffered,
differential inputs. Single-ended signals may also be input.
Transmission lines supplying input signals must be properly
terminated close to the CLC006. Either A.C. or D.C. coupling
as in Figure 2 or Figure 3 may be used.Figures 2, 4 and Figure
5 show how Thevenin-equivalent resistor networks are used

to provide input termination and biasing. The input D.C. com-
mon-mode voltage range is 0.8V to 2.5V below the positive
power supply (V
within the specified common-mode range. For an 800 mV
input signal, typical input bias levels range from 1.2V to 2.1V
below the positive supply.
