High-Speed I/O Standards Support
RSDS, Mini-LVDS, and PPDS I/O Standard Support in the Cyclone III Device
Family
The RSDS, mini-LVDS, and PPDS I/O standards are used in chip-to-chip applications
between the timing controller and the column drivers on the display panels such as
LCD monitor panels and LCD televisions. The Cyclone III device family meets the
National Semiconductor Corporation RSDS Interface Specification, Texas Instruments
mini-LVDS Interface Specification, and National Semiconductor Corporation PPDS
Interface Specification to support RSDS, mini-LVDS and PPDS output standards,
respectively.

Designing with RSDS, Mini-LVDS, and PPDS
Cyclone III device family I/O banks support RSDS, mini-LVDS, and PPDS output
standards. The left and right I/O banks support true RSDS, mini-LVDS, and PPDS
transmitters. On the top and bottom I/O banks, RSDS, mini-LVDS, and PPDS
transmitters are supported using two single-ended output buffers with external
resistors. The two-single ended output buffers are programmed to have opposite
polarity.
