6.4. I/O Standards
The PHY Lite for Parallel Interfaces FPGA IP for Stratix® 10 devices allows you to set I/O standards on the pins associated with the generated configuration. The I/O standard controls the available strobe configurations and OCT settings for all groups.
However, even though most I/O standards support differential or complementary I/Os, such as SSTL, HSTL, and POD, the PHY Lite for Parallel Interfaces FPGA IP for Stratix® 10 can only be configured to use single-ended I/O data pins.
I/O Standard | Valid Input Terminations (Ω) | Valid Output Terminations (Ω) | RZQ (Ω) | Differential/Complementary I/O Support
Important:
PHY Lite for Parallel Interfaces FPGA IP for Stratix® 10 devices does not support differential data pins. |
