WIDEBAND, INVERTING OPERATION
Figure 48 shows the THS3121 in a typical inverting
gain
configuration
where

impedances and signal gain from Figure 47 are
retained in an inverting circuit configuration.

The THS3120 and THS3121 have the capability to

signals down multiple cables. To ensure high signal

0.1-dB gain flatness should be at least 7x the

component video and RGB video signals that require
fast transition times and fast settling times for high
