Part Number: AM5728

From customer:

Today customer is using DM368 and wants to add more cameras and improve system performance. Customer is considering AM57x family.

-          Worst case video load on the system:

o   Eight analog cameras at D1@15FPS and eight I/P cameras at 1080P60

o   OR

o   Sixteen I/P cameras at 1080P60 and no analogue cameras

o   Record either of those video options simultaneously, and be able to display any two video stream simultaneously.

-          Will the AM5728 be able to handle the above worst case load?

    Hi Rogerio,

    You can read in the TRM that maximum of 16 camera sources are support per Pixel Input Clock Domain but you should pay attention on the pixel clock which is up to 165 Mhz per port. AM5728 has 3 VIP modules. Each one of VIP 1 and VIP2 have 2 ports - Port A and Port B, where Port A can be configured as a 24/16/8 bit port, and Port B is a fixed 8bit port. VIP3 does not use Port B of both slices and Port A supports only 16bit interface. You can find detailed description in TRM section 9.1 VIP Overview.


    As conclusion AM5728 is not able to support 16 cameras at 1080P60 due to pixel clock limitation.
