Hi,

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

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

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.

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.
