The THS3202 may also be employed as a very good video distribution amplifier. One characteristic of distribution
amplifiers is the fact that the differential phase (DP) and the differential gain (DG) are compromised as the
number of lines increase and the closed-loop gain increases. Be sure to use termination resistors throughout the
distribution system to minimize reflections and capacitive loading.
