Other Parts Discussed in Thread: LM5143
Good morning,
It is wonderful to see you are implementing a phase locked loop for synchronising the LM5143.
This is just what I need.
The frequency range for the SYNCIN signal is specified as -20% and +20% of the nominal set frequency.
This range is unfortunately right at the limits of my requirement.
Would the LM5143's SYNCIN be able to lock onto a -30% to +30% variation in frequency, to give me some margin?
If yes, this will give me peace of mind and make me eager to use the LM5143 in my new design.
Another question I have: What is the duty cycle of the SYNCOUT signal?
If it is 50%, it will be wonderful - unfortunately it is not specified on the datasheet.
Your urgent reply will be appreciated.
Sincerely,
Stephen.
