Getting started on the AD9545

Category: Hardware
Product Number: AD9545
Software Version: ACE Version

I intend to test the timing deviation output of the AD9545 evaluation board with a 1 PPS input and a 10 MHz output.

Are there standard operating procedures for using the AD9545 ACE plug-in given a desired input frequency and desired output frequency? Considering my lack of experience in the field, I have not had much success deciphering the datasheet and user guide found here: AD9545 Evaluation Board User Guide [Analog Devices Wiki].

I was able to get the cso file - found on this forum post: AD9545 IN:10MHz External OUT:122.88MHz - Q&A - Clock and Timing - EngineerZone - working on the evaluation board. But naively modifying the configuration wizard parameters did not seem to work.

Is it possible to receive explicit instructions for setting up the AD9545 evaluation board with a 1 PPS input and a 10 MHz output?

  • Hi,

    I wrote today the attached to explain how to work with the AD9545 eval board and with the eval software to be able to provide 1PPS clock and obtain 10MHz. I supposed you also wanted to output a 1 Hz clock in phase to the 1PPS besides the 10MHz output, so I set the DPLL0 in internal zero delay mode.

    I also attach the cso file I used. Please take out the txt extension before loading it into the AD9545 eval software.

    If you want to make changes in ACE: if the change can be done in the configuration wizard, do it there. Other changes can be done in the GUI and then click Apply Changes button to write them into the chip.

    If you want to load this cso file, click directly Apply Changes (so the settings are downloaded into the chip from ACE), then click Cal All, which means the system clock PLL, APLL0 and APLL1 are calibrated. Then, if the configuration has the Auto Sync feature set to Immediate (like I have in the attached cso file), the outputs are generated right away, independent on the state of the reference clocks. Otherwise, just click Sync All.

  • Hi Petre,

    I very much appreciate your time spent in crafting this reply. This perfectly answered my question.

    Thank you.
