Application Examples
Creating a design with the SelectI/O features requires the
instantiation of the desired library symbol within the design
code. At the board level, designers need to know the termi-
nation techniques required for each I/O standard.
This section describes some common application examples
illustrating the termination techniques recommended by
each of the standards supported by the SelectI/O features.
Termination Examples
Circuit examples involving typical termination techniques for
each of the SelectI/O standards follow. For a full range of
accepted values for the DC voltage specifications for each
standard, refer to the table associated with each figure.
The resistors used in each termination technique example
and the transmission lines depicted represent board level
components and are not meant to represent components
on the device.
GTL
A sample circuit illustrating a valid termination technique for
GTL is shown in Figure 44. Table 23 lists DC voltage speci-
fications.
GTL+
A sample circuit illustrating a valid termination technique for
GTL+ appears in Figure 45. DC voltage specifications
appear in Table 24.
