Input Clocks
It is imperative to note that the processor’s minimum and maximum SYSCLK, core, and VCO frequencies
must not be exceeded regardless of the type of clock source. Therefore, systems in which the processor is
operated at its maximum rated e500 core frequency should avoid violating the stated limits by using
down-spreading only.
4.2
Real-Time Clock Timing
The RTC input is sampled by the platform clock (CCB clock). The output of the sampling latch is then
used as an input to the counters of the PIC and the TimeBase unit of the e500. There is no jitter
specification. The minimum pulse width of the RTC signal should be greater than 2 × the period of the
CCB clock. That is, minimum clock high time is 2
× tCCB, and minimum clock low time is 2 × tCCB. There
is no minimum RTC frequency; RTC may be grounded if not needed.
4.3
eTSEC Gigabit Reference Clock Timing
Table 7 provides the eTSEC gigabit reference clocks (EC_GTX_CLK125) AC timing specifications for
the MPC8533E.
4.4
Platform to FIFO Restrictions
Please note the following FIFO maximum speed restrictions based on platform speed.
For FIFO GMII mode:
FIFO TX/RX clock frequency <= platform clock frequency/4.2
For example, if the platform frequency is 533 MHz, the FIFO TX/RX clock frequency should be no more
than 127 MHz.

Notes:
1. Rise and fall times for EC_GTX_CLK125 are measured from 0.5 and 2.0 V for L/TVDD = 2.5 V, and from 0.6 and 2.7 V for
L/TVDD = 3.3 V.
2. EC_GTX_CLK125 is used to generate the GTX clock for the eTSEC transmitter with 2% degradation. EC_GTX_CLK125
duty cycle can be loosened from 47%/53% as long as the PHY device can tolerate the duty cycle generated by the eTSEC
GTX_CLK. See Section 8.5.4, “RGMII and RTBI AC Timing Specifications,” for duty cycle for 10Base-T and 100Base-T
reference clock.
