DS90UH940-Q1: mipi output at digital reset

Masaru Oinaga

Hi Team,

When 01[0] is set to 1 and the device is in digital RESET with a duration of ~2ms, the measured mipi output voltage was ~500mV.

1. Can we avoid this mipi voltage being in neither LP mode (>=550mV) nor HS mode (<=450mV)?

2. Is there anything we have to consider in such situation?

Thanks and Best Regards,

Hi,

Can you provide scope captures of the CSI lanes when this reset is happening and provide your schematic?
