2.2.3.1. Guidelines: Programmable Output Slew Rate Control

Table 7.  Slew Rate Implementation and Mode SupportUncompensated slew rate is supported only for OCT without calibration. Compensated slew rate is supported only for OCT with calibration.
Slew Rate Setting Implementation Slew Rate Mode Support
  • Fast
  • Medium
  • Slow
GPIO mode Supports only the uncompensated slew rate mode.
  • External memory interface
  • PHY Lite
Supports only the compensated slew rate mode. The compensated slew rate mode achieves better slew rate control by reducing variation of the ramp rate.
Fastest
  • GPIO mode
  • External memory interface
  • PHY Lite
Supports only the slew rate bypass mode. The implementation disables slew rate control and the buffer switches at the fastest ramp rate.
