DS90UB962-Q1: 962 related issues

Part Number: DS90UB962-Q1

1,Can the setting of the 962 mode pin be modified again through I2C after power on.

2: What is the maximum bandwidth supported by 962 LANE for 3G?

3: The current MODE setting is RAW10, with a camera of 1920 * 1440, 30fps, and YUV422-8. Can you help confirm whether it is supported (including calculation methods) in terms of bandwidth and PCLK.

    Max supported bandwidth at the CSI TX is 1.664Gbps per lane. Keep in mind there is ~ 25% CSI overhead.

    Total bandwidth = Hres x Vres x Fps x blanking x #bits/pixle

                              = 1920 x 1440 x 30 x 1.25 x 10 = 1.659 Gbps
