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 delivers +3.3 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.
PoCXP for cards with 24 V DC power source
The external 24 V supply is attached to the auxiliary power input connector through a 4-pin cable and delivered to each power transmitting unit.
The AuxiliaryPowerInput feature reports the status of the connection made by the power cable between the external power supply and the Coaxlink card auxiliary power input connector.
The CxpPoCxpPowerInputStatus feature reports the status of the 24 V input.
