Notes:
1. Input to output phase skew after an ICAL is not controlled and can assume any value.
2. Lock and settle time performance is dependent on the frequency plan, the XAXB reference frequency, and LOCKT
setting (see application note, “AN803: Lock and Settling Time Considerations for Si5324/27/69/74 Any-Frequency
Jitter Attenuating Clock ICs”. Visit the Silicon Labs Technical Support web page at:
https://www.silabs.com/support/pages/contacttechnicalsupport.aspx to submit a technical support request regarding
the lock time of your frequency plan.
