Switching Characteristics
Table 1–39 lists typical transmitter pre-emphasis levels for Arria II GZ devices (in dB)
for the first post tap under the following conditions (low-frequency data pattern [five
1s and five 0s] at 6.25 Gbps). The levels listed in Table 1–39 are a representation of
possible pre-emphasis levels under the specified conditions only and that the pre-
emphasis levels may change with data pattern and data rate.
f To predict the pre-emphasis level for your specific data rate and pattern, run
simulations using the Arria II HSSI HSPICE models.
