Figure 26: Reference Circuit Design for TP0 Interface
The reference circuit design of TP1 is similar to that of TP0. Please refer to TP0 reference circuit design
for TP1.
3.20. Camera Interfaces
Based on standard MIPI CSI input interface, SC66 module supports 3 cameras (4-lane + 4-lane + 4-lane)
or 4 cameras (4-lane + 4-lane + 2-lane + 1-lane), with maximum pixels up to 24MP for SC66. The video
and photo quality are determined by various factors such as camera sensor, camera lens quality, etc.
