Hi, ALL,
I designed a RF module pwoered by LT8390.
It has a internal OSC, which decided by a external RT pin resistor.
the follwoing picture is the RT resistor vs. switching freq.
So,
1. Could any one estimate the switching freq pricision? I guess it is a RC OSC, right?
2. What freq precision difference between the different date/patch produced LT8390 with the same RT resistor?
3. What freq precision difference between 200K and 180K RT resistors?
Many thanks.
Best,
Tony Liu
