Operation
INPUT INTERFACING
The CLC007 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 CLC007. Either A.C. or D.C. coupling
as in Figure 2 or Figure 3 may be used. Figures 2, 4 and
