1.8.3 MIPI CSI-2 Output Signals
Provided on the DS90UB96X-Q1EVM, J6 and J7 are Samtec QSH-type connectors that can be mated
with a matching QTH type connector on the top. This Samtec connector provides a means to route CSI-2
signals out of the DS90UB96X-Q1. The J6 and J7 corresponds to CSI0 Port and CSI1 Port output
connection signals respectively, and includes access to I
2
C and other miscellaneous GPIO signals. Zero
ohm resistor pads are available if a connection to other signals is required. The mating connector part
number is QTH-020-01-H-D-DP-A.
There are third party solutions like the HDR-128291-XX breakout board from Samtec which can be used.
The HDR- 128291-XX is a breakout board with a mating connector to J6 & J7 and standard SMA male
connectors. More info on this breakout board can be obtained from Samtec website. Another third party
option is the ZX100 by Zebax Technologies. More information on this board can be obtained from Zebax
website.
