QUICC Engine Block Operating Frequency Limitations

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.
This table lists the maximal QUICC Engine block I/O frequencies and the minimal QUICC Engine block core frequency for
each interface.

DDR and DDR2 SDRAM
This section describes the DC and AC electrical specifications for the DDR and DDR2 SDRAM interface of the
MPC8360E/58E.

Notes:
1. The QUICC Engine module needs to run at a frequency higher than or equal to what is listed in this table.
2. ‘F’ is the actual interface operating frequency.\
3. The bit rate limit is independent of the data bus width (that is, the same for serial, nibble, or octal interfaces).
4. TDM in high-speed mode for serial data interface.
