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 4 or Figure 5 may be used. Figure 4, Figure 6 and Figure 7 show how Thevenin-

equivalent resistor networks are used to provide input termination and biasing. The input D.C. common-mode

voltage range is 0.8V to 2.5V below the positive power supply (VCC). Input signals plus bias should be kept within

the specified common-mode range. For an 800 mVP-P input signal, typical input bias levels range from 1.2V to

2.1V below the positive supply.
