6.3 MIPI CSI-2 Output Signals
Provided on the DS90UB960-Q1EVM, J1 and J3 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 DS90UB960-Q1. The J1 and J3 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 J1 & J3 and standard SMA male connectors.
