Hi everyone, I'm currently working on stm32f4 nucleo board. I have a analog device based HMC767 PLL (datasheet and user manual link below) eval kit. i want to sweep a bandwidth of 150Mhz( strt freq= 8.0ghz stp freq= 8.15ghz).

I'm using SPI communication for generating the sweep.But Unfortunately Im not able generate the sweep as desired and the PLL remains in the default state giving 9 gHz single tone frequency.please help me if any one has implemented the HMC based PLL ...

Resolved! ADC(VDDA) Input Volatge

Hi,I am not quite sure about this. I have a STM32L100 µC operating at 1.8V, the analog pin sees a 3.0V coming from a battery and I want to use the ADC to be able to monitor the voltage of the battery.I plan to supply the VDDA Pin with 3.3V (the VRef+...
