Low-voltage differential signaling (LVDS) is a powerful high-speed interface in many system applications. The I/Os are designed to be compatible with the EIA/TIA electrical specifications for LVDS system and board design. With the use of an LVDS current-mode driver in the IOBs and the optional internal differential termination feature, the need for external source termination in point-to-point applications is eliminated. UltraScale devices provide a flexible solution for creating an LVDS design.
The LVDS I/O standard is only available in the HP I/O banks. It requires a V CCO to be powered at 1.8V for outputs and for inputs when the optional internal differential termination is implemented.
• DIFF_TERM_ADV = TERM_100
• DIFF_TERM = TRUE
The LVDS_25 I/O standard is available in the HR I/O banks. It requires a V CCO to be powered at 2.5V for outputs and for inputs when the optional internal differential termination is implemented.
• DIFF_TERM_ADV = TERM_100
• DIFF_TERM = TRUE
