Part of register setting:
Reg 01h<14> = 1
Reg 1Ah<9:0> = 40h ; Reg 1Ah<11:10> = 1:1 ; Reg 1Ah<13:12> = 1:0; Reg 1Ah<19:14> = 0h ;
Reg 1Bh<3:0> = 2h ;
Accroding to data sheet( if I dont understand anything wrong), the pin 33(LD_SDO) would always output the lock detect signal in this setting.
However, when I have gotten the locked signal through Spectrum Analyzer, the pin 33 still would not output a high level singal. So where is the problem?
