Notes:
1. Caution: The CCB to SYSCLK ratio and e500 core to CCB ratio settings must be chosen such that the resulting SYSCLK
2. Rise and fall times for SYSCLK are measured at 0.6 and 2.7 V.
3. Timing is guaranteed by design and characterization.
4. This represents the total input jitter—short term and long term—and is guaranteed by design.
5. For spread spectrum clocking, guidelines are ±1% of the input frequency with a maximum of 60 kHz of modulation regardless

Notes:
1. Timing is guaranteed by design and characterization.
2. EC_GTX_CLK125 is used to generate GTX clock for TSEC transmitter with 2% degradation. EC_GTX_CLK125 duty cycle
can be loosened from 47/53% as long as PHY device can tolerate the duty cycle generated by GTX_CLK of TSEC.
