2.1 Connectors for DSI8X Input Ports
The EVM has two input options for DSI video. If a custom breakout board is to be designed using these
options, a schematic and an allegro PCB symbol for either connector is provided by TI upon request.
(A) J4 - Samtec QSH-type connector (P/N QSH-020-01-H-D-DP-A)
J4 is a Samtec QSH-type connector that can be mated with a matching QTH-type connector on the
top. It provides DSI input connections to both DSI Ch A and Ch B signals. It also provides access to
I
2
C and other miscellaneous signals such as IRQ. XC connections are open vias just in case there is a
need for connection to other signals. The mating connector part number is QTH-020-01-H-D-DP-A. For
an SMA-type connection, use the Samtec HDR-128291-XX breakout board. The HDR-128291-XX is a
breakout board with a mating connector to J4 and standard SMA male connectors via cables. More
information on this breakout board is provided upon request.
(B) J1 – Hirose FX-type connector (P/N FX6A-40S-0.8SV2)
J1 is a Hirose FX-type connector that can be mated with a matching FX plug on the top. The part
number for the mating connector is FX6A-40P-0.8SV2. J1 provides DSI input connection only to the
DSI Ch A signals. It also provides access to I
2
C and other miscellaneous signals such as IRQ.
2.2 Connectors for DSI85 Output Ports
There are two output port options available on the EVM for the LVDS output signals. If a custom breakout
board is to be designed using these options, a schematic and an allegro PCB symbol for either connector
can be provided by TI.
(A) J6 - Samtec QSH-type connector (P/N QSH-020-01-H-D-DP-A)
J6 is a Samtec QSH-type connector that can be mated with a matching QTH-type connector on the
top. It provides DSI input connections to both LVDS Ch A and Ch B signals. It also provides access to
