EC_GTX_CLK125 frequency
EC_GTX_CLK125 cycle time
EC_GTX_CLK rise and fall time
EC_GTX_CLK125 duty cycle
EC_GTX_CLK125 jitter
Notes:
1. Rise and fall times for EC_GTX_CLK125 are measured from 0.5 and 2.0 V for LV
2. EC_GTX_CLK125 is used to generate the GTX clock for the eTSEC transmitter with 2% degradation. The EC_GTX_CLK125
CLKIN/PCI_CLK duty cycle
CLKIN/PCI_CLK jitter
Notes:
1. Caution: The system, core, USB, security, and TSEC must not exceed their respective maximum or minimum operating
2. Rise and fall times for CLKIN/PCI_CLK are measured at 0.4 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. The CLKIN/PCI_CLK driver’s closed loop jitter bandwidth should be < 500 kHz at –20 dB. The bandwidth must be set low to
6. Spread spectrum clocking is allowed with 1% input frequency down-spread at maximum 50 KHz modulation rate regardless
