Hello Che,

here is my review feedback.

- Make sure the CSI traces are 100-ohm differential and length matched.
- Make sure I2C pins are pulled up as per Table 6-12
- Make sure both DOUT AC-coupling caps have the same voltage rating (50V)
- LPF1 requires a 1.8nF cap not 2.2nF
- On the power-supply pins (VDD_1P8_xx) our recommendation is to use 10uF caps not 1uF. Refer to Figure 7-3
