47 RL range: 90 ≤ RL ≤ 110 Ω.
48 The specification is only applicable to default VOD and pre-emphasis setting.
49 The True Differential Signaling input buffer is supported on 1.05 V, 1.1 V, 1.2 V, and 1.3 V VCCIO_PIO banks. The maximum input voltage driven into the True Differential Signaling input buffer must not exceed VICM(max) + VID(max)/2.
50 True Differential Signaling - 1.3 V standard is compatible with LVDS and capable to interface with LVDS subsets such as:
  • RSDS
  • Mini-LVDS
  • Any I/O standards using equivalent electrical specifications
51 For further information on True Differential Signaling - 1.3 V feature support and guidelines on interfacing True Differential Signaling -1.3V standard with LVDS and it's subset compliant standards, refer to the related information.
52 The VICM(DC) voltage must not exceed 1.2 V when on-chip differential termination (RD OCT) is disabled with the use of external on-board termination.
