  • Added 1.8 V LVDS I/O standard support.
2021.11.01 21.1
  • Added 10M08 V81 package and 10M16 Y180 package for single supply devices in the LVDS Buffers in Intel® MAX® 10 Devices table.
  • Updated figure title to LVDS Support in I/O Banks of 10M02 (Single Power Supply U324 Package), 10M04, and 10M08 (Except V81, M153, and U169 Packages) Devices.
  • Added diagram: LVDS Support in I/O Banks of 10M08 V81, M153, and U169 Packages Devices.
Date Version Changes
December 2017 2017.12.15
  • Added short descriptions about the true and emulated LVDS buffers.
  • Added single power supply U324 package.
  • Updated the topic about using the Soft LVDS IP core (receiver) in external PLL mode to remove the ALTPLL IP core slow clock output (c1) connection to the Soft LVDS rx_synclock input for even deserialization factor. The rx_synclock is not used by the Soft LVDS IP core when the deserialization factor is even.
  • Updated the section about high-speed I/O timing budget:
    • Updated the high-speed I/O timing budget topic to clarify that Intel® MAX® 10 devices implements SERDES in LEs.
    • Removed information about obtaining RSKM report in the Intel® Quartus® Prime software. The software does not support generating RSKM report for Intel® MAX® 10 devices.
    • Removed the topic about assigning input delay to the LVDS receiver.
    • Added link to timing constraints section of the Intel Quartus Prime Standard Edition Handbook Volume 3: Verification.
  • Updated the condition and description for the Enable pll_areset port parameter to specify that it is not available in external PLL mode.
  • Throughout the document, added links to related information to improve usability.
  • Further edits for Intel rebranding.
February 2017 2017.02.21 Rebranded as Intel.
October 2016 2016.10.31
  • Added related information links in the topic about LVDS channels support.
  • Restructured and updated the topic about the RSKM.

  • Added true RSDS and emulated RSDS (three resistors) transmitter support for single supply Intel® MAX® 10 devices.
  • Updated the transmitter and receiver channels placement topics to describe about minimizing skew when you group LVDS channels for an application.
  • Updated the description of the rx_data_reset interface signal to specify that you must externally synchronize it with the fast clock.

November 2015 2015.11.02
  • Updated the high-speed LVDS circuitry figure to correct the flow from C1 in ALTPLL to inclock of ALTERA_SOFT_LVDS. Previously, the figure shows a bidirectional flow.
  • Updated the steps for determining the external PLL clock parameters for the receiver to clarify the clock names listed by the Intel® Quartus® Prime compilation report.
  • Updated the topic about Soft LVDS parameter settings:
    • Added links to topics about PLL and high-speed I/O performance in the device datasheet.
    • Corrected the conditions required to use the Enable tx_data_reset port and Enable rx_data_reset port parameters. You must turn on the Use external PLL option first.
    • Updated the allowed values for the Tx_outclock division factor and Outclock duty cycle parameters.
