Notes:
1. Caution: The system and core must not exceed their respective maximum or minimum operating frequencies.
2. Rise and fall times for SYS_CLK_IN 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 SYS_CLK_IN driver’s closed loop jitter bandwidth should be <500 kHz at –20 dB. The bandwidth must be set low to
6. Spread spectrum is allowed up to 1% down-spread @ 33 kHz (max rate).
allow cascade-connected PLL-based devices to track SYS_CLK_IN drivers with the specified jitter.
