Transmit equalization selection bus for SerDes 2 lanes c and d (SD2_RX/TX[2:3])
Default value = 4’b0100 (SGMII)
MSB (bit 20) is the differential peak-to-peak amplitude selection:
0 = Vdd-diff-pk=pk
1 = 5/6 Vdd-diff-pk=pk
LSBs (bits 21:23) are the equalization amplitude selection:
000 = No equalization
001 = 1.09x rel.amplitude
010 = 1.2x rel.amplitude
011 = 1.33x rel.amplitude
100 = 1.5x rel.amplitude
101 = 1.71x rel.amplitude
110 = 2.0x rel.amplitude
