1.4.4 MIPI CSI-2 Output Signals

Provided on the DS90UB954-Q1EVM, J5 and J6 are Samtec QSH-type connectors that can be mated
with a matching QTH type connector. This Samtec connector provides a means to route CSI-2 signals out
of the DS90UB954-Q1. The J5 connector is on the top side of the EVM for accessability, and the J6
connector is on the bottom for mating with a TDAx evaluation kit. The signals to the connectors are the
same, including access to I
at a time. If the J6 connector on the bottom is to be used, populate the zero ohm resistors on the bottom
of the board which extened the traces to the J6 connector. 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 J5 or J6, providing access to each
pin through 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.
