Hello Minghan
We do not have appnote to explain the design of the notch filter and your specific question. However, I am sharing the below link which seems useful to give some insights on how notch filter is implemented.

Hello Ben
It seems one filter was intended to be configured as LPF and another as HPF to implement the Notch filter. But again, since both have same coefficients, they do the same task. Did you try disabling one the filters? Do you see any difference…
Part Number: TIDM-1001 Hi Team,
Here's an issue from the customer may need your help:
Do you mind sharing the method or experience of selecting input capacitance and output capacitance in the reference design, or can you explain the reasons for your…

Part Number: TIDM-HV-1PH-DCAC HI Can you please tell me how the notch filter calculations were performed. Cannot find it in the design guide. Please provide equations used in the calculation. Thank you Damith
Part Number: TIDM-02002 Other Parts Discussed in Thread: TMDSCNCD280049C There is a low-pass RC filter based on R254 and C245 with 56.2Ohm and 10pF accordingly. This gives roughly a cut-off frequency at 283MHz.
What is the calculation formula or a reason…
Wayne,
1.The notch filter frequency depends on the ac line frequency.
