Trion T120 BGA324 Development Kit User Guide
Camera Power-Up Circuit
The Trion
®
T120 BGA324 Development Board includes a basic power up sequence circuit for
MIPI CSI-2 cameras. You control the circuit using SW1. When SW1 is on, the power up goes
from VSUP1 to VSUP2 to VSUP3 in sequence.
Note:
To apply power in sequence, set the jumpers for J4, J5 and J6 as described in
on page 15.
Headers
The board contains a variety of headers to provide power, inputs, and outputs, and to
communicate with external devices or boards.
