What should I do If I use a LVDS screen instead of a DSI as in Disco boards?

Gencay · ‎2022-09-07

my stm32mp157f-dk2 board has a DSI (ECMF04-4HSWM10 filter) screen but my custom board is going to have a LVDS screen so what should I do different to protect the screen? (Filtering or ESD protection etc.)

Hi @Gencay

I added topic 'EMI Filtering and Signal Conditioning'

I assume you already have a DSI2LVDS converter (or RGB2LVDS brige), so question could be also for the bridge supplier.

Hi,

I found that ECMF04-4HSWM10 could be used as for DSI (LVDS is lower requency than DSI).

ECMF04-4HSWM10 includes common mode filter for WLAN/BT bands.

For ESD protection only, HSP051-4M10 could be used instead (similar but not same footprint).

Maybe EMI/ESD experts might come with more suitable answer.
