PPS Function Programming
Refer to the OE Pin Function table to have proper PPS function selected for OE pin(s). Note that the register default is set to Output Enable (OE) function for OE pins.
Input Pin Function
The input pins in 5X2503 have multiple functions. The OE1 pin can be configured as output enable control (OE) or chip power-down control (PD#) or Proactive Power Saving function (PPS). Furthermore, the OE1 pin can be configured as single or Dynamic Frequency Control (DFC). ©2017 Integrated Device Technology, Inc 5 December 18, 2017 Document Outline Description Typical Applications Features Output Features Key Specifications Block Diagram Power Group Output Source Selection Register Setting Tables Pin Assignments Figure 1.
