Source code of ADF4355/ADF4355-2/ADF4355-3/ADF4356/ADF5355/ADF5356 Evaluation Software is attached.
Hello. Could someone answer the following about the ADF4355-3 synthesizer:
1. If I want to use software power down mode after I programmed the IC, is there a register sequence to get back to power on mode or do I just flip the bit back? Is it possible…
I don't find in ADF4355-3 data sheet the allowable temperature range for VCO not being re-calibrated.
Is it -40°C to -105°C so 145°C?
Unfortunately, VCO supply is 5 V for ADF4356.
I have been having repeatable issue with the ADF4355-3 where heating up the IC will cause unstable RF output. What I'm seeing is the Lock Detect mux output is toggling between '1' and '0' repeatedly. When I update the registers with a new frequency…
The ADF4355-3 data sheet says all power supplies must be 3.3V
I am looking at "EZ-ADF4355-3SD1Z User Guide". In the schematic and parts list it has the VCO etc supplied from a 5V regulator (reference VR2). Is this a mistake?
Our board output of ADF4355-3 has spurious at 1. 8kHz. The spurious is constant in different output frequency, bleed current and CP current.
We attempt to replace DC-DC with external power supply，but the spurious still unchanded.
We have a few questions…
I am trying to use ADF4355-3 as an upgrade for an existing product that successfully uses ADF4350.
I do not have the evaluation board, but I am using ADIsimPLL to verify some register settings and my loop filter
I am pretty sure I am communicating SPI…
I had designed recently ADF4355-3 own board.In that I want to know
1. whether Vvco and Vdd of ADF4355-3 can be given same 3.3v from one regulator or not?
2. what happens if these Pin23(Vref) and Pin24(Vbias) are connected to 3.3v?
3.Does any thing…
