Figure 4-3. Power-over-Coax Network For Use With DS90UB933
WARNING
Verify that the Power-over-Coax voltage is properly set before plugging into RX0 or RX1. Power
supply is not fused. Over-voltage will cause damage to boards directly connected due to incorrect
input power supplies.
DS90UB913A-Q1EVM is designed for a maximum of 5V PoC
. To use
DS90UB913A-Q1EVM with DS90UB954-Q1EVM, open J17 or J18 to disable PoC, and either power
the DS90UB913A-Q1EVM separately or by applying 5V to the J17 or J18 pin on DS90UB954-
Q1EVM.

Signal
Description
J18
VPOC_RX0
This sets the voltage for Power-over-Coax on RX0
Jumper installed: +9V power supply from VPOC_LDO0_9V
Jumper Open: No PoC connected. Apply power to pin1 or leave open and power serializer
separately.
J17
VPOC_RX1
This sets the voltage for Power-over-Coax on RX1
Jumper installed: +9V power supply from VPOC_LDO1_9V
Jumper Open: No PoC connected. Apply power to pin1 or leave open and power serializer
separately.
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 I
2
C 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.
