Analog PLL for fixed frequency PLO

Question asked by JLF on Feb 7, 2016

I would like to implement an analog PLL for a fixed frequency phase-locked oscillator. RF/LO frequencies could be as low as 1 MHz or even on the hundred KHz range. Can anyone suggest a suitable doubly-balanced mixer?


I found AD831 and AD8343 as potential candidates. Do you confirm this choice or there are other more suitable products?


Info on frequency dividers with parallel data bus control (not SPI controlled) would be much appreciated.
