Label
Determines the output swing of a data buffer for CDR/RCLK.
In PCML mode:
00b: Power down
01b: 500 mV
10b: 900 mV
11b: 1200 mV
For LVDS, the output swing is reduced to:
00b: Power down
01b: RRL 390 mV
10b: GPL 700 mV
11b: 940 mV
For LVPECL, the output swing is increased to:
00b: Power down
01b: 900 mV
10b: Standard (low specification side) 1200 mV
11b: Standard (nominal) 1600 mV
For InfiniBand, the output swing is increased to:
00b: Power down
01b: 900 mV
10b: 1200 mV
11b: Standard (nominal) 1400 mV
N/A
Flips the polarity of the output data.
0b: Normal
