DS90UB954-Q1: RX MODE Pin when 933 is connected.

Part Number: DS90UB954-Q1

Hi.

I am designing a circuit using 954.
The other device uses 933 and sends data with YUV422(8bit).
At this time, for the RX mode of 954, please tell me which mode number should be selected in Table 2.

    Hi Masanori,

    If the UB933 is sending YUV422(8-bit), then the UB954 should be set to RAW10 RX MODE. After selecting RAW10 mode, there are a few additional register configuration steps that need to be done in order to operate in 8-bit mode:

    1. Select an RX Port to write to in register 0x4C in the UB954 (Port 0 or 1)
    2. Enter the data type code, as defined in the MIPI specifications, in register 0x70[5:0]. The data type code for YUV422(8-bit) should be 0x1E.
    3. In register 0x7C[7:6], enable the 8-bit mode that matches how the 8-bit data is being inputted into the UB933.

    Best,
