2.4. I/O Standards

The PHY Lite for Parallel Interfaces IP 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. One RZQ group supports up to two different output terminations and one input termination. RZQ pin cannot be used as data pin.

Supported I/O standards are listed in the following table. Differential data are supported for all I/O standards. Differential ref_clk is not supported in the same lane as PHY Lite for LVSTL I/O standards.
