    I don't see anywhere from below window to configure rx_syncclock or rx_cloreclk.

    So the code generated doesn't have this port for me to do anything.

    I suppose there should be somewhere can pull out rx_syncclock or rx_cloreclk.

    Then we can use it my project and connect to external pll output.

    Unfortunately, I don't find it. I need this help.

    Hello,


    Which version of Quartus and device do you use?


    Thank you.

    Hello,


    This option is enabled when the LVDS is implemented in logic. When you turn on this option, it adds an input port, which when asserted performs an asynchronous reset of all the logic in the ALTLVDS_RX IP core excluding the PLL.


    Thank you.
