Hi Tguy
Thank you for your reply !
I wirte configuration register about following the datasheet on the page 59.
0x0C ---------0xD1
0x0D----------0xD9
0x0A----------0xCF
0x0A----------0xA0
read the 0x0E 's bit 7 can't get "1".
ref_clk is 122.88MHz.
Noise on the 10KHz is -90dBc/Hz
ref_clk meet the requirements!
Thank you !
Jack
