Figure 2-5. General Purpose PLL (GPLL) Diagram
Standard PLL (SPLL)
Some of the larger devices have two to six Standard PLLs (SPLLs). SPLLs have the same features as GPLLs but
without delay adjustment capability. SPLLs also provide different parametric specifications. For more information,
please see the list of additional technical documentation at the end of this data sheet.
Table 2-4 provides a description of the signals in the GPLL and SPLL blocks.
