SN65DSI83-Q1: Failure in Radio Immunity

ABDUL RAHUMAN

Hi Team,

Currently, I am in the chamber conducting RI (Radiated Immunity) testing. At 260 MHz, we are observing a slow flicker on the display, which recovers at 270 MHz. However, at exactly 280 MHz, the display turns off completely and does not recover on its own — the backlight remains continuously on, and the display only comes back after performing a power cycle.

Hi Abdul,

Could you tell us more about this test setup. Is there a way to isolate whether the issue is originating within this DSI83 bridge device or could it also be related to the REFCLK or SoC sources?

When the issue occurs, could you also get a register dump and check whether 0xE5 register shows errors on this issue.

Best regards,
Ikram
