DS90UB964-Q1: Question regarding support for RGB565, RAW8 pattern generation

Sathyakam Medavaram

Part Number: DS90UB964-Q1

Hi TI Experts,

We have DS90UB964-Q1 Desrializer on our MIPI CSI2 solution boards connected to the processor.
I like to know if DS90UB964-Q1 can generate test pattern for below

1. RGB565 color bar with 4096x4096 resolution
2. RAW8 color bar with 4096x4096 resolution

From the Data sheet I could infer the default Dat type 0x24 (RGB888).
Can I change this to 0x22 (RGB565) or 0x2A (RAW8) and generate the desired color bar patterns?

If DS90UB964-Q1 Desrializer does not support these formats, then please let me know which other Deserializer can be used.

Thanks,
Sathyakam

    Sathyakam,

    yes, UB964 can support the data type RAW8 / RGB656. You can set the reg. 03 (in the digital Page 0 Indirect Register list).

    one concern is that what is the frame rate request in you case? you can calculate the maximum PCLK in your 4096*4096 resolution, which should catch the CSI2 bandwidth request of UB964.

    best regards,

    Ssteven

    Hi,

    Thank you for the reply.

    We are not aiming for particular FPS as for now, but just want to generate and capture CSI traffic with specific format & resolutions.

    So we will vary FPS to be with in the bounds of PCLK.

    Also regarding pattern generation, can you tell us what is meant by "Reference color bar pattern" as opposed to fixed color bar pattern?

    Does it mean the color bar changes for every frame in case of reference color bar pattern?
