Lattice Semiconductor
The programmable drive feature also allows the user to match to the impedance of the transmission line.
Table 8-4 shows the drive current setting required to match 50¾ transmission line with 50¾ and 200¾ termina-
tions.
Table 8-4. Impedance Matching Using Programmable Drive Strength
The actual impedance matching may vary on the transmission line design and the load. To find the best matching,
it is recommended to drive the transmission line with different combinations of I/O standards and drive strengths
that best match the line impedance. Lattice provides IBIS buffer models for the users to further analyze the imped-
ance matching.
The figure below shows how this impedance matching is done for a 50¾ transmission line with 200¾ termination
using LVCMOS18 I/O buffers programmed to drive 16mA, 12mA, 8mA and 4mA. From this experiment it is empiri-
cal that the best matching is achieved with the 8mA drive setting.
