Other Parts Discussed in Thread: TIDA-00299
Hi all
Would you mind if we ask DP83822IF?
On the reference design TIDA-00299, there are C28 ~ C31 = 4.7pF.
What are these C28 ~ C31 = 4.7pF used for? To improve noise?
In generally, these capacitances are not required.
And then, is the value 4.7pF suitable value? How much value is more suitable value?(We guess that it depends on the board layout,,,,)
Kind regards,
Hirotaka Matsumoto
