1629 Coaxlink Duo PCIe/104-EMB
Main power distribution network
The
main power distribution network
delivers power to
all the on-board electronic devices
including FPGA, memory chips, CoaXPress transceivers, I/O drivers and receivers, fan motor.
It also de3.3 V and +12 V to the
3300 HD26F I/O module for Coaxlink Duo PCIe/104
plugged on the extension connector:
●
The +3.3 V is used for powering the on-board electronics: I/O drivers, I/O receivers
●
The +12 V is used for delivering power on the I/O connector. A PTC inserted at the input
prevents potential fire hazards.
The network is fed by the Host PC through the +12 V power rail of the PCIe/104 connector. A
protection fuse prevents potential fire hazards. The
+12 V LED
indicates the presence of +12 V
after the protection fuse.

The
board status LED
reflects the global status of all the power converters of the main
distribution network.
Camera power distribution network
The
auxiliary power distribution network
delivers power to the CoaXPress cameras using the
PoCXP capability available on all connections of the CoaXPress Host connector.
The network is fed by a 24 VDC external power supply attached to the
camera power input
connector
using a power cable terminated by a 4-pin Molex plug connector. A protection fuse
inserted at the input side prevents potential fire hazards.
The 24-volt DC power is applied to each camera connection through a PoCXP transmitter unit.
Each PoCXP transmitter unit implements an electronic fuse/switch. A PTC inserted at the input
of each transmitter unit prevents potential fire hazards.
