• It is necessary for HMC984 to build a PLL. Due to incomplete online data, there are few register related descriptions and usage instructions. In order to facilitate program writing and debugging, I want to ask for detailed technical data related to registers.

  • I'm sorry, But I still have some questions to consult with you.At the bottom of page 3 of the manual, about Bias Bias Bias voltage, I connected 3V voltage from 12 pin, and then through 1nF capacitance to pin, the measured voltage was less than the minimum voltage of 1.58V. Is it because my multimeter is not 10G ohm or the board attenuation problem that caused the phase detector to fail to lock?
