Part Number: TRF372017
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
RF Output frequency:
I recommend the standard fractional loop filter that TI uses on the EVM. You can find the details in the schematics that is on the TI web: http://www.ti.com/lit/zip/slwc095.
I recommend a PFD frequency around 32.5 MHz which corresponds to an Rdiv = 2.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
