Part Number: LM25141-Q1

Hi,

Has the schematic implemented the LMx5141 passed the CISPR25 ed.3 level5?

Though EVM and PMP15019 seems not to pass it...

Best Regards,
Kuramochi

  • Hello Kuramochi san,

    Can you please let me know what schematic you are refering to?

    Thanks.

    Kind Regards,

    David Baba.

  • Kuramochi,

    No the LM5141-Q1 EVM fails CISPR 25 in the FM band (30MHz to 108MHz).  It does pass between 150kHz and 30MHz.  Were working on a new PCB layout that I hope will resolve the problems.

    Terry-san,

    Thank you for your information.

    When is the new version EVM released?

    Best Regards,

    Kuramochi

  • In reply to Kuramochi Tadahiko:

    Kuramochi,

    It will be at least two months before I have a new PCB layout and I have made the measurment.  We will probably will not release a new EVM, it will be a PMP desige.
