4.4 MIPI CSI-2 Output Signals

There are two options provided for passing out the deserialized data on the DS90UB954-Q1EVM . The first is a Samtec QSH-type connector, J24, on the top of the board that can be mated with a matching QTH type connector. The mating connector part number for the J24 connector is QTH-020-01-H-D-DP-A. On the bottom of the board is a Samtec QTH-type connector, J26, meant for mating with a TDAx evaluation kit. The signals to the connectors are the same, including access to I2C and other signals including PDB and GPIO. Only one connector should be used 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 extend the traces to the J26 connector.

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 J24 or J26, 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.
