Other Parts Discussed in Thread: DS90UB954-Q1, ALP
I'm using the DS90UB954-Q1 EVM connected to self designed PCB with DS90UB953. The serializer is connected to 2 lane MIPI camera module OV2311 via flat cable.
The deserializer can be controlled by ALP or a connected Raspberry PI. I am able to set the sreaming mode of the the camera using I2C. The MIPI signals
are enabled and can be measured with an oscizlisope as input data for the serializer. Unfortuantely I cann't receive the signals at the deserializer output.
DS90UB953 has an 10k pull-down at the MODE pin --> CSI-2 synchronous mode
DS90UB954 has an voltage divider 78k7 / 97k6 --> CSI-2 synchronous back channel
DS90UB954: Device PASS and LOCK status bit are set (register 0x04=DF)
DS90UB953: LINK_DET, HS_PLL_LOCK and RX_LOCK_DETECT set to 1 (CRC_ERR too) 0x52=47
Jumper on the DS90UB954Q1-EVM to set CSI-2 mode.
BIST srcipt '953_054_BIST' runs succesfully.
Do you have an idea why no output signals are available at the deserializer output?
