Reset, Clocking, and Initialization
4.4.4.2
Clocks for these high speed interfaces on the MPC8544E are derived from a PLL in the SerDes block. This
PLL is driven by a reference clock (SD_REF_CLK/SD_REF_CLK) whose input frequency is a function
of the protocol and bit rate being used as shown in
4.4.4.2.1
Section 4.4.3.6, “I/O Port
that the CCB clock frequency must be considered for proper operation of such interfaces as described
below.
