ML605 Support for LVCMOS 1.8 V

Hello,

 

Based on the ML605 user guide, the IO banks are connected to 2.5 V, so it can be configured as LVCMOS 2.5 or LVDS, but it can't be configured as LVCMOS 1.8v

 

So, is there any Hardware workaround to support the LVCMOS 1.8V  IO?

In my application, I am concerned with the FMC connector and If I can interface with a dauhgter card using VDD = 1.8v

 

Thanks,

In ML605 all bank voltages are fixed to 2.5V. VADJ also fixed to 2.5V in ML605. So you cannot interface LVCMOS 1.8V signals directly with ML605 IO’S.

 

 

To interface LVCMOS 1.8V  signals  one solution is  designing new FMC daughter card with level conversion chips
