1.6. Guidelines: I/O Restriction Rules
For different I/O standards and conditions, you must limit the number of I/O pins. This I/O restriction rule is applicable if you use LVDS transmitters or receivers. Apply this restriction if one or more LVDS I/O standards reside in the I/O bank.
I/O Standard | Condition | Max Output Pins Per Bank (%) |
---|---|---|
2.5 V LVTTL/LVCMOS | 16 mA current strength or 25 Ω OCT | 25 |
12 mA current strength | 30 | |
8 mA current strength or 50 Ω OCT | 45 | |
4 mA current strength | 65 | |
2.5 V SSTL | — | 100 |
