SD2_REF_CLK/_B reference clock cycle time
SD2_REF_CLK/_B frequency tolerance
SD_REF_CLK/_B rise/fall time (80%-20%)
SD_REF_CLK/_B duty cycle (@50% X2VDD)
SD_REF_CLK/_B cycle to cycle clock jitter (period jitter)
SD_REF_CLK/_B phase jitter (peak-to-peak)
Note:
1. Only 100/125/150 MHz have been tested, other in between values will not work correctly with the rest of the system.
2. In a frequency band from 150 kHz to 15 MHz, at BER of 10E-12.
3. Total peak-to-peak deterministic jitter “Dj” should be less than or equal to 50 ps.
