HI,

How could you know the CP value matches the corresponding frequency
range?

Thanks.

Best regards,

There's 3 bands. Their values are on page 11 of datasheet, depending on
tuning system used (DVB/ISDB/ATSC). low/mid/high.

I duno about CP values/band, in my hardware its
50uA for 174-349 | 428-659
125uA 349-397 | 659-729
250uA 397-428 | 759-862
but my hardware is ISDB-T.

good luck.
