TDA4VM: FPDlink serdes

Hello Barry,

Thank you for your question. What configuration do you need for your setup? The DS90UB953 is able to lock with the partner deserializer on power up and does not require a particular initialization sequence. If there are specific features you would like to use in your system, then there may be some register settings to enable such features, but for a basic bring up no configuration script is necessary.

Hi Darrah,

Our purpose is to light up the four ARO233 cameras connected to the CSI0 end of TDA4VM.

1.TDA4VM EVM + TI Fusion Application Board (TI 960 Des.)

2. Camera : AR0233 (with ISP) + TI 953 (Ser)

Can you give us the serdes_config configuration required by ser+des?

In order for us to receive images from 4 cameras on the TDA4 side.

Regards,

Barry

Hello Barry,

The 953 serializer does not need any configuration to receive data from a camera, and as long as the 953 and 960 hardware are set to bring up the devices in the same mode, they should lock and begin to transmit data between each other automatically. The only configuration that would be necessary for your system, is configuring the 960 to output the data to the TDA4. To do this program set register 0x33[0] = 1 and register 0x20 = 0x00 to forward all four RX ports to CSI0. If there are additional requirements such as speed or number of CSI lanes, there are additional configuration options that can be set. However, if the default 4 lanes and 800Mbps is suitable, no extra configuration is needed. This is assuming that the TDA4 and cameras are already configured to send and receive data respectively.

Hi Darrah,

Can you give me a complete serdes configuration?

Could you send us the GUI debugging tool of TI FPD LINK?

For us to debug and generate the complete configuration required for camera (ds90ub953) + ds90ub960.

Regards,

Barry
