DS90C241: Camera SerDes and Display SerDes

Part Number: DS90C241

Hi there,

I'd like to ask you a basic question about FPD-link/SerDes. I might be confused with the concept of resolution, but I don't understand how Camera SerDes and Display SerDes in TI portfolio are exactly different.

1. Are two of them basically compatible except for several devices with specific interface(e.g. DSI for display and CSI for camera)? I meant, for example, DS90C241 is classified in Camera SerDes in subfamily, but it still can be used for Display SerDes if it met resolution and data rate?

2. I need to classify the devices in terms of data rate. In Display SerDes, can I think (color depth) * (pixel clock) as approximate max data rate? I was about to classify them with which display size the serializer support (e.g. 2K (2880x1080), WUXGA (1920x1200), or 1080p60 (1920x1080) etc., but there are a lot of devices which don't describe this information explicitly.

3. Can I classify Camera SerDes in terms of data rate in the same way above? I was thinking it can be based on 1+/2+/... MP, but a lot of device don't describe it as well.

Thank you for your time.

    Hello Minkyung,

    Camera/Display are really arbitrary terms and are sometime related to the common interfaces used for camera/display applications. For example many cameras use CSI-2 interface while display interfaces don't commonly use CSI-2. Within our portfolio it is sometimes used to classify groups of compatible serdes products, but the rule doesn't always hold for older devices like DS90C241. 

    Even trying to describe this in terms of resolution or megapixels doesn't really tell the full story because the same resolution can have different refresh rates, color depth, data formats, etc. 

    Is there a specific application you are trying to solve where we can help to recommend a suitable device for you?

    Best Regards,

    Casey
