Arria 10 GX , Cyclone 10 GX transceiver phy compatibility

Hi Manolis,

As I understand it, you're observing some issues in the datapath between the C10 transmitter and the A10 receiver. Regarding your specific question on the electrical compatibility between C10 TX and A10 RX, I’ve reviewed their datasheets and, based on the specifications, there should be no issue interfacing the two devices electrically.

To help facilitate further debugging, I’d like to check on a few points:

1. Status Signals:

Could you please share the status signals from both the C10 TX and the A10 RX? This information would help us assess the current state of the link and determine the next steps in debugging.

2. Signal Integrity Check:

Have you had a chance to probe the C10 TX SMA output with an oscilloscope to inspect the eye diagram? This would help rule out any signal integrity issues at the transmitter side.

3. Loopback Test:

You might also consider performing an SMA loopback from the C10 TX to the C10 RX. This can help verify whether the C10 TX is functioning correctly in isolation.

Please let me know if you have any concerns. Looking forward to your update.
