using Cyclone V SoC 5CSEBA5U23I7N. We plan to use some inputs configured as LVDS with 2.5 VCCIO.
I am looking at Cyclone V Device Datasheet CV-51002 | 2019.01.25 and see in table 23:
Absolute VMAX for a receiver pin = 1.2 V Max.
But elsewhere I see in Table 23:
Maximum peak to peak differential input voltage VID after device configuration = 2.2 V.
Also in table 20:
VICM Max = 1.8 V
It seems to me that if I allow the VICM to be 1.8 then I will have exceeded the VMAX for a pin and if I have a VID of 2.2 V. I will have exceeded VMAX since VMIN is -0.4 V for a receiver pin.
Please tell me how I have misinterpreted this data sheet.
