4.3 Power-over-Coax Interface

The DS90UB95x-Q1EVM offers two Power-over-Coax interfaces (PoC) to connect cameras through a coaxial
cable with FAKRA connectors. Power is delivered on the same conductor that is used to transmit video and
control channel data between the host and the camera. By default, 5V power supply is applied over the coax
cable. Refer to for other PoC configurations.
For port RX0, the PoC network is configured for a DS90UB953-Q1EVM (or variant), and for RX1 the
PoC network is configured for a DS90UB933-Q1. Only use a serializer EVM with the correct PoC
network. To use PoC with two DS90UB953-Q1EVM (or variant) or DS90UB933-Q1 EVM's, one of the
PoC networks must be reworked. You may also open the PoC circuit and power the serializer EVM
directly from another supply.
For Power-over-Coax (PoC) on the EVM, the circuit uses a filter network as shown in
network frequency response corresponds to the bandwidth compatible with DS90UB953-Q1EVM (or variant)
chipsets.
