5.8.2.3. RSDS, Mini-LVDS, and PPDS I/O Standard in Intel® Cyclone® 10 LP Devices
To support RSDS, mini-LVDS, and PPDS output standards, Intel® Cyclone® 10 LP devices conform to the following specifications:
- National Semiconductor Corporation RSDS Interface Specification
- Texas Instruments mini-LVDS Interface Specification
- National Semiconductor Corporation PPDS Interface Specification
Intel® Cyclone® 10 LP I/O banks support RSDS, mini-LVDS, and PPDS output standards:
- The right I/O banks support true RSDS, mini-LVDS, and PPDS transmitters.
- The top and bottom I/O banks support emulated RSDS, mini-LVDS, and PPDS transmitters with external resistors.
A resistor network is required to attenuate the output voltage swing to meet RSDS, mini-LVDS, and PPDS specifications when using emulated transmitters. You can modify the resistor network values to reduce power or improve the noise margin.
For an RSDS interface, you can use a single external resistor instead of three. The single-resistor solution reduces the external resistor count while still achieving the required RSDS signaling level. However, the performance is lower than with a three-resistor network.
