5.8. Outputs
Each driver has a configurable voltage swing and common mode voltage covering a wide variety of differential
signal formats. In addition to supporting differential signals, any of the outputs can be configured as single-ended
LVCMOS (3.3 V, 2.5 V, or 1.8 V) providing up to 20 single-ended outputs, or any combination of differential and
single-ended outputs.
5.8.1. Output Crosspoint
A crosspoint allows any of the output drivers to connect with any of the MultiSynths as shown in Figure 22. The
crosspoint configuration is programmable and can be stored in NVM so that the desired output configuration is
ready at power up.

5.8.2. Output Signal Format
The differential output swing and common mode voltage are both fully programmable covering a wide variety of
signal formats including LVDS and LVPECL. In addition to supporting differential signals, any of the outputs can be
configured as LVCMOS (3.3 V, 2.5 V, or 1.8 V) drivers providing up to 20 single-ended outputs, or any combination
of differential and single-ended outputs.
