Why does my Intel® Arria® 10 device simplex receiver have low jitter tolerance when no transmitter is used in that channel? - Why does my Intel® Arria® 10 device simplex receiver have low jitter tolerance when no transmitter is used in that channel? Description Due to a problem in the Intel® Quartus® Prime Software version 16.1 and earlier calibration code, your Intel® Arria® 10 device simplex receiver may have low jitter tolerance when no transmitter is used in that channel. Resolution To work around this problem, you can instantiate a simplex TX transceiver and merge it into the same channel as the simplex RX transceiver. After calibration is complete you can write a 1'b0 to address offset 0x10F to stop the TX serializer clock from toggling and save power. If user-mode recalibration must be run again, you must first turn the TX serializer clock back on by writing 1'b1 to address offset 0x10F. This problem is fixed in Intel® Quartus® Prime Software version 16.1.2.
