Hi, can anyone help out with which hardware I can use to write to the ADF4351 synthesizer?
Please see attached link for information on the Evaluation Board for the ADF4351 and also the accompanying User Guide for this board.
Any microcontroller with an SPI interface will be suitable for writing to the ADF4351.
The chip uses a standard SPI interface (LE, DATA and CLK). More details can be found in Figure 2 of the ADF4351 data sheet: http://www.analog.com/static/imported-files/data_sheets/ADF4351.pdf#page=5
The ADF4350 control software source code may also be helpful: http://ez.analog.com/message/52311#52311
