Part Number: SN65LVDS324

SN65LVDS324 and ar0230cs used together. There are three questions:
1 how to configure SN65LVDS324 to make its output test 1080P60fps image?
2.ar0230cs work at hispi 60fps output,  how to configure SN65LVDS324?
3. how to confirm that the ar0230cs from the SN65LVDS324 side is the normal output data?

    Hello Xiabo,

    You can use the for Aptina 1-channel four-lanes configuration. According with the datasheet's table 1 you can choose  12 or 16 bits per pixel. Take in account that only streaming-SP mode is supported.


    Also you can check the both figures 18 and 20 for more details about hardware connections.

    For 1080p video we recommend the following settings

    Aptina 1-channel, 4-lane, 16-bits per pixel, 1080P@60fps

    FRAME_WIDTH_MSB (0x0B, bits 4:0) & FRAME_WIDTH_LSB (0x0C)

    FRAME_ HEIGHT_MSB (0x0D, bits 4:0) & FRAME_ HEIGHT_LSB (0x0E)

    SENSOR_CFG[2:0]: 110

    Target SCLK Frequency: 297 MHz

    Target CLKOUT Frequency: 148.5 MHz

    PLL_CFG[1:0]: 11

    Please check the datasheet for further details.

     

    Regards,

    Gerardo

    Hi,

         We use  mode: Aptina 1-channel, 4-lane, 12-bits per pixel, 1080P@60fps, as figures 17.

         Sensor without the output of clock, how to configure the test mode on SN65LVDS324?
