    I managed to get the driver update. But no matter what I do , I can not seem to get the device programmed. When I use the load function nothing happens. Are there required jumpers?

    Hi Bnovus,

    Can you explain your issue in detail?

    I think I damaged the eval board. I will have it repaired next week and provide more detail

    Thanks

    I managed to repair the eval unit. I am trying to use the LMX2571 to synch an OCXO (10 MHz) with another 10 MHz signal. I will also be using the part to synch a 100MHz OCXO with a 10 MHz. I am connecting a LVCMOS signal to the OSCin port. I am using the charge pump to develop an error signal to the external OCXO and I am bring the external OCXO (.5 v rms) into the Fin port. I am not sure what the correct settings on the port loader and I am either not porograming the device at all or programming the part incorrectly.

    If you can advise the correct settings for the portloader that would be  big help

    Thanks again

    Bill,

    The LMX2571 evaluation board comes with a 20 MHz crystal oscillator on the board, so I don't know if you have bypassed or changed that, but if not, this is the first issue.

    However, in general, I would recommend do the debugging on the board before doing the modifications.  If you go to the CodeLoader and go to "Modes", then you can select the default mode, which is configured for a 20 MHz crystal.

    To verify communications:

    1.  Go to the port setup and click "Identify".  This blinks a light on the USB2ANY device to verify communication between the computer and this.   However, it does NOT  verify communication between the USB2ANY interface and the LMX2571 PCB.

    2.  Load the default mode by using Mode-> Default Mode xxxx.   This loads in the default settings to CodeLoader, but does NOT send them to the device.

    3.  Press Cntr+L to send the registers to the device.   Observe the current on the power supply and it should change.  Also, click the powerdown bit and you should see this impact the current.

    If you can't get past the first 3 steps, then there is a communication issue.  If you can, then be sure that you are looking at he PLL F1 tab and not the "PLL F2" tab, which are shadow registers.  Also ensure that you have the right crystal frequency.  If it's 10 MHz or 100 MHz, make sure that you modify the board for this.  Also, for the multiplier, it has a limited input and output range, so right mouse this on the main PLL gui to make it "x1" to get this out of the picture to get started.

    Hi Dean

    I meet similar issue when usgin LMX2581, can you help check this?

    I can't get past the first 3 steps

    If I press Cntr+L to send the registers to the device, We will show as below Error message

    Jimmy,

    I just wanted to check and see if this issue is resolved.

    The TICSPro should automatically update the USB2ANY driver and ask you to update the driver.

    This involves pushing the BSL button on the driver.  The TICSPro manual gives more details on this.

    I couldn't find a TICSPro user's guide, but I did find the CodeLoader users' guide that has a procedure for it there.
