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.

f For more information about the Cyclone III device family RSDS, mini-LVDS, and

PPDS output electrical specifications, refer to the Cyclone III Device Data Sheet and

Cyclone III LS Device Data Sheet chapters.

f For more information about the RSDS I/O standard, refer to the RSDS specification

from the National Semiconductor website (www.national.com).

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.

Figure 7–5 shows a RSDS, mini-LVDS, or PPDS interface with a true output buffer.
