Notes:
1.
Mask revision E devices have tighter output ranges but can be used in any design that was in a previous revision. See
Revisions, page
55.
2.
The numbers in this table are based on the conditions set forth in
3.
This value must be compatible with the receiver to which the FPGA’s output pair is connected.
4.
Output voltage measurements for all differential standards are made with a termination resistor (R
of the differential signal pair.
5.
Only one of the differential standards RSDS_25, LDT_25, LVDS_25, and LVDSEXT_25 may be used for outputs within a bank.
Each differential standard input-pair requires an external 100Ω termination resistor.
6.
Each LVPECL_25 or BLVDS_25 output-pair requires three external resistors for proper output operation as shown in
LVPECL_25 or BLVDS_25 input-pair uses a 100Ω termination resistor at the receiver.
