1k Series restors on ADF4351 and PE43703
Posted: Thu Nov 20, 2025 12:24 am
I want to have an ADF4351 and an attenuator in my Portsdown 4.
I am unsure about the 1k resistors. I think it comes down to a choice between these 2 options?
or
And presumably the same for Data on pin 31?
Also I assume I need a 1k in the line from to pin 33 to ADF4351 LE and another for pin 10 to the PE43703 LE so:
Can someone confirm which option to use for CLK and DATA and if I have the LE 1ks correct?
