2.4.3. Intel® MAX® 10 On-Chip I/O Termination
The on-chip termination (OCT) block in Intel® MAX® 10 devices provides I/O impedance matching and termination capabilities. OCT maintains signal quality, saves board space, and reduces external component costs.
The Intel® MAX® 10 devices support serial (RS) OCT for single-ended output pins and bidirectional pins. For bidirectional pins, OCT is active for output only.
Figure 13. Single-ended I/O Termination (RS) This figure shows the single-ended termination scheme supported in Intel® MAX® 10 device.
Direction | OCT Schemes | Device Support | I/O Bank Support |
---|---|---|---|
Output | RS OCT with calibration | Intel® MAX® 10 16, 25, 40, and 50 devices | Right bank only |
RS OCT without calibration | All Intel® MAX® 10 devices | All I/O banks |
