The HFA1212 Dual Video Buffer can be used to implement
differential line drivers and receivers with a minimum of
external components (see Figure 2). Common mode
rejection is set by the internal matched thin film resistors
which are pin strapped to set the various closed loop gains
that are required.
VIN is terminated into 75Ω and drives both amplifiers in U1.
U1A has a gain of -1 while U1B has a gain of +1. These
amplifiers create a differential signal with a gain of 2. Series
75Ω resistors provide impedance matching to the
transmission line.
