I wish to know that the How the VDD_Interface voltage level will affect RX/TX DATA & Controls, SPI lines voltage levels?
If i connect the interface to LVDS 2.5 V , will all data lines, controls lines,GPO & SPI lines voltage would be 2.5V if i feed VDD_INTERFACE voltage as 2.5V?
I want to know how this voltage level will affect on IO lines voltage levels? If i use LVDS mode what could be the voltage level of all Data, Control & SPI lines.
Thanks for your support in advance.
Digital interface levels are specified in the datasheet. Please look in the specification tables.
GPO run from a different supply, not VDD interface. The supply is VDDA_GPO and its maximum level is 3…
If you are using 2.5V supply then connecting to 2.5V bank should work.
That is correct.
GPO run from a different supply, not VDD interface. The supply is VDDA_GPO and its maximum level is 3.3V.
Yes it is there, Since i am using LVDS (2.5V) interface. I am connecting my data lines, control lines 7 SPI to 2.5V bank of FPGA. Is that ok? or am i wrong ?
Please give some clarification on this
which 2.5V supply?
Now i am connecting AD9364in LVDS mode, and all data lines connected to 2.5V FPGA Bank, which is powered with 2.5V.
Is this correct or not?
What are you connecting VDD_INTERFACE to?
