RSDS

Reduced-swing differential signaling (RSDS) is similar to an LVDS high-speed interface using differential signaling. RSDS has a similar implementation to LVDS_25 and is only intended for point-to-point applications. RSDS is only available in HR I/O banks and requires a V_CCO voltage level of 2.5V. The IOSTANDARD is called RSDS_25.

Table: Allowed Attributes for the RSDS I/O Standard  summarizes the allowed attributes for the RSDS I/O standard. Support is implied for primitives that are derivatives of the primitives listed in Table: Allowed Attributes for the RSDS I/O Standard  (for example: *_DIFF_OUT, *_DCIEN, *_IBUFDISABLE, or *_INTERMDISABLE). Refer to the SelectIO Interface Primitives section for all supported derivatives.
