CC2564/CC2564B RF Calibration

Hi,

Not sure I understood the term: "frequency trim".
Can you please explain?

Hi:
Our product using CC2564 is under FCC Test now, according to the test result,the frequency has some trim compare with standard,like i'm using channle 8(2410MHZ) for continuous TX,but the actual frequency is 2410MHZ+100KHZ ( the 26M crystal has some trim result in this ).
I'm using CSR BC8670 for this product before, every CSR's chip needs a 'frequency trim'.

the XTAL config as this:
0x01, 0x1c, 0xfd, 0x14, 0x01, 0x88, 0x13, 0x00, 0x00, 0xd0, 0x07, 0x00, 0x00, 0xff, 0xff,

and this
0x04, 0xff, 0xff, 0xff, 0xfa, 0x00, 0x00, 0x00, 0x00,
