You can enable the left-shift series termination control feature in the ALTIOBUF
megafunction in the Quartus II software. The Quartus II software only allows
left-shift series termination control for 25-Ω calibrated R
reference resistors connected to the RUP and RDN pins. You can only use left-shift series
termination control for the I/O standards that support 25-Ω calibrated R
This feature is automatically enabled if you are using a bidirectional I/O with 25-Ω
calibrated R
For more information about how to enable the left-shift series termination feature in
the ALTIOBUF megafunction, refer to the
Guide.
Expanded R
OCT calibration circuits always adjust R
connected to the RUP and RDN pin; however, it is possible to achieve R
other than the 25-Ω and 50-Ω resistors. Theoretically, if you need a different R
value, you can change the resistance connected to the RUP and RDN pins accordingly.
Practically, the R
output buffer size and granularity limitations.
The Quartus II software only allows discrete R
and 60 Ω . You can select the closest discrete value of R
in the Quartus II software to your system to achieve the closest timing. For example, if
you are using 20-Ω R
R
