LMX2615-SP: Altium Library + Pinout

Part Number: LMX2615-SP

Hi Vibhu, 

I have a question regarding the LMX2615-SP. Do we have the Altium Library file for the 64 pin CQFP package of the LMX2615-SP? 

In addition, we noticed that a couple of the pins on the evaluation board schematic have different names / pin numbers when compared to the datasheet. I'm assuming the datasheet is correct, but is there a reason that there is a difference with the EVM schematics?

Let me know if we should take this conversation offline.

Thanks,

AH

  • Hello AH,

    I believe you should be able to download the file from the product folder. In the Design & development section, CAD/CAE symbols.

    There shouldn't be any major differences in the pins, can you point them out, on quick glance I see that the FS pins are FS0-FS7 on the datasheet vs FS1-FS8 on the EVM schematic, is this what you are referring to? This seems to have been a typo when making the altium design. You are correct, go by the datasheet.

    Thanks,

    Vibhu

  • Hi Vibhu, 

    Please find a few differences below:

    • Pin 5 in the EVM is called enable, but CAL in the datasheet. It shouldn't make a difference, but different names
    • Pins 45 and 52 don't exist in the datasheet, but are on the EVM
    • NC pins are grounded in the datasheet, but on the EVM they are not connected. I'm assuming this doesn't matter if the NC pins are grounded or left NC?

    Thanks,

    AH

  • Hi Alpha,

    Pin 5 can be enable and calibration, it is just a pin name issue.

    Pin 45 is defined in datasheet while 52 is NC.

    NC pins can be ground or floating.

    The EVM schematic was drawn long before the datasheet is published, the datasheet has the most up-to-date pin name but we haven't revise EVM schematic accordingly.
