High Data Rate Mode
High Data Rate Mode is a low power mode that supports data rates up to 25.8 Gbps. It
is the default mode if none of the modes are selected in the Quartus Assignment
Editor or Quartus Settings File (.qsf). This mode provides an alternative path for high
gain mode. High Data Rate Mode can be used to compensate for the loss similar to
CEI 28G VSR. High data rate mode supports four bandwidth modes: Full, three-
fourths, one-half, and one-fourth bandwidth modes. Full bandwidth mode can provide
AC peaking at approximately 8 dB at a peaking frequency of 14 GHz. High data rate
mode can be operated in three-fourths, one-half, and one-fourth bandwidth with 9
GHz, 5 GHz, and 2.5 GHz peaking frequencies. In high data rate mode, AC gain values
