Can Serial Lite II in a Stratix IV talke to Serial Lite III in an Arria 10???

[AUcamera]

i have a legacy Stratix IV design using Serial Lite II to interface to another PCB.  That second PCB has been upgraded to an Arria 10.  Since I have to use Serial Lite III in the Arria 10, can it be configured to interface to the Serial Lite II in the Stratix?

Hi Robert

No, the SerialLite II and SerialLite III IPs are incompatible due the different encoding schemes used by each. SerialLite II uses 8B/10B encoding and SerialLite III uses 64B/67B encoding. Packet structure differences also prohibit compatability.

You can find the above information at Intel FPGA Knowledge Base articel below.

In the case, you could consider stick to Serial Lite II in A10, below is the wiki link to the design example and also the Serial Lite II design and document (https://community.intel.com/t5/FPGA-Wiki/Using-SerialLite-II-IP-on-Arria-10-devices/ta-p/735662)

can the Stratix IV run Serial Lite III?

No, Stratix IV doesn't support Serial Lite III. Stratix IV only supports up to Serial Lite II. 

Table 1 of SerialLite III IP Core User Guide indicated that Serial Lite III is supported in Stratix 10, Stratix V, Arria V GZ and

Arria 10 (no Stratix IV).
