Table 1â38 lists the typical transmitter pre-emphasis levels in dB for the first post tap
under the following conditions: low-frequency data pattern (five 1s and five 0s) at
6.375 Gbps. The levels listed in Table 1â38 are a representation of possible
pre-emphasis levels under these specified conditions only, the pre-emphasis levels
may change with data pattern and data rate.
To predict the pre-emphasis level for your specific data rate and pattern, run
simulations using the Arria II GX HSSI HSPICE models.
