1 The maximum data rate is calculated based on a maximum lane rate as listed in Table 7. The data rate is calculated based on the formula lane rate = (10/8) × NP × data

rate × (M/L), where the NP, M, and L values depend on the selected mode.

2 The maximum DAC rate per mode depends on the voltage tolerance as well as the lane rate for a given configuration, as listed in Table 3. The maximum possible lane rate

is as listed in Table 7.
