Figure 7. Output Clock Termination Circuit

12.1

Output Differential Termination

LVDS (default configuration), LVPECL, HCSL, and CML differential signaling types can be supported by
changing the output termination circuits.

12.1.1

LVDS, CML

The board is shipped to support LVDS, CML in its default differential. The signals are ac coupled with
ceramic 0.1 uF capacitors instead of the corresponding series resistors RSExx (Refer to

) which

are not populated.
