4:1 RGB Differential Video MUX
Connecting the channel select pins in parallel (S0-1 to S0-2
and S1-1 to S1-2) converts the 8 individual RGB video inputs
into 4 differential RGB input pairs. The amplifier RGB outputs
are similarly paired resulting in a fully differential 4:1 RGB
MUX amp shown in Figure 18. Connecting HIZ1 and HIZ2 to
+5V disables the 4:1 differential MUX, and enables the
connection of additional differential-connected MUX amplifiers
to the same outputs, thus allowing input expansion to 8:1 or
more.
