QUICC Engine Block Operating Frequency Limitations
This section specify the limits of the AC electrical characteristics for the operation of the QUICC Engine
block’s communication interfaces.
NOTE
The settings listed below are required for correct hardware interface
operation. Each protocol by itself requires a minimal QUICC Engine block
operating frequency setting for meeting the performance target. Because the
performance is a complex function of all the QUICC Engine block settings,
the user should make use of the QUICC Engine block performance utility
tool provided by Freescale to validate their system.
Table 12 lists the maximal QUICC Engine block I/O frequencies and the minimal QUICC Engine block
core frequency for each interface.

Notes:
1. DLL lock times are a function of the ratio between the output clock and the coherency system bus clock (csb_clk). A 2:1 ratio
results in the minimum and an 8:1 ratio results in the maximum.
2. The csb_clk is determined by the CLKIN and system PLL ratio. See Section 22, “Clocking,for more information.
