Hi all,
My customer plans to use TRF372017 for Japanese Digital TV.
Could you tell me the recommended constant of PLL loop filter for this application?
Also I would like to know the recommended value of RDIV of TRF372017.
When using the Loop filter calculation tool, should we calculate a constant based on the CH33 of the center channel for this application?
Reference input frequency: 65.0158MHz
