Now we have the following problems. I hope someone can put forward suggestions
1. Our refsel and eepromsel are connected to the ground, so 1110110 is selected for SLAVE ADRRES. After power on, the device will be reset for 500ms through reset pin. Then configure from the 0x3F register to the 0x00 register according to the protocol shown in figure 27. Then write a 1 to recal, select the EEPROM page,unlock the eeprom , start the commit operation, force a crc update,read back crc value and store it in the eeprom.This procedure is according to page 29 of datasheet. However, the output frequency is always 94MHz, which will not change for our configuration changes. Then we try to write the register(like CH2_CTRL3)and read it back, and the results are all 0000,which is just like I never write it in successfully.
2. If we remove the resistance of eepromsel, that is, let eepromsel pin high Z, and change SLAVE ADRRES to 1110100, there will be no output signal
