    I could not find any test done with this datarate. You should try to use the same method that was used with the 1.25 Msps which I sent you a link to. Start from the 500 kbps settings and increase the datarate to 625 kbps. 

    It could be that FS_DIG0 and AGC_CFG2 and the deviation have to be adjusted but you have to do tests yourself to see what you have to change to get the wanted performance.

    in the document cc1201.

    section 4.5: 

    data rate: 1250kbps means the 4GFSK max data rate.

    does the 625kbps means the 2fsk max data rate?

    in the rf studio7 software , the max data rate is 500k in the 2fsk mode.

    i cannot cfg the data rate exceed the 500k in the 2fsk mode?

    SmartRF Studio is giving you a warning since 500 kbps is the highest datarate we have tested. Since 1250 kbps is tested using 4-GFSK it should be possible to use 625 kbps 2-FSK but as said you have to do testing to check the performance.
