5.1.5. Receiver Buffer

The receiver input buffer receives serial data from rx_serial_data and feeds the serial data to the clock data recovery (CDR) unit and deserializer. Select High Speed Differential I/O, CML, Differential LVPECL, and LVDS for the I/O standard of the Intel® Arria® 10 receiver pin in Intel® Quartus® Prime Assignment Editor or QSF file. CML, Differential LVPECL, and LVDS are only used on AC coupled links.
