Limited interoperability of CRUVI HS modules with AXE5000 and AXC3000

[FvM]

Hello,

I recently ordered CR00200-01 (1 Gbps Ethernet) and CR00049-01 eMMC CRUVI modules, considering to use them for test setups with AXE5000 Agilex 5 Eval Board.

Looking into possible implementation details, I notice now that these modules can be most likely not used with Agilex FPGA Boards due to incompatible Vadj range. Agilex 3 and 5 have a maximal VCC_HSSI of 1.3 V while Marvell 88E1512 PHY on CR00200 and eMMC on CR00049 require at least 1.8 V IO supply.

I might be that operation at unspecified lower VDDO respectively VCCQ is possible, I didn't yet test.

What I would expect however is a hint in module product information about minimal required Vadj.

Any experience with operation of CRUVI modules beyond 1.8 V Vadj?

Regards
Frank

yes the operation is only possible for MIPI and HDMI boards. The 1.3V is not so good but Agilex has no other options

Hello Antti, thanks for confirming the issue. I wonder if anybody tried to run the modules at 1.3V IO voltage?

1.3V should be OK
