DVico Fusion HDTV Dual Express PCB showing component labels

A hybrid DVB-T PCIe card from DViCO.

It is not supported under Linux. However, experimental support for the DVB-T side is available (see below for details).


Able to deliver one analogue channel and one digital channel simultaneously or 2 digital channels. High definition resolution is 1920 x 1080. Features a power switch pass-through to allow it to turn the host system on automatically.

Components Used

  • 2 x Xceive 3008ACQ (tuner IC)
  • 2 x Intel WJCE6353 (digital demodulator)
  • Conexant CX23885 (A/V Decoder / PCIe bridge)
  • Pericom P15C.... (switch)
  • PIC16F73 (external audio adc ? -- its used as such on the Fusion5 RT (note- the PIC16F73 is currently unsupported under Linux, so audio from external analog sources (a/v inputs) will not work); or maybe its being used for remote control (although that might be natively handled by the cx23885)?; or maybe its being used in conjunction with RTC duty ?)
  • some Atmel eeproms
  • some others (RF switch)...

Making it Work


The driver requires the standard xc3028 firmware (xc3028-v27.fw), to obtain the firmware see instructions within the extract_xc3028.pl script (available within linux/arch/Documentation/video4linux/).


There is currently no in kernel drivers for the device. However, the card's digital functionality is supported in the main V4L-DVB tree available here: http://linuxtv.org/hg/v4l-dvb/

The patches applied to the tree above were derived by work originally completed by Chris Pascoe, the older version of these patches can be found here: http://www.itee.uq.edu.au/~chrisp/Linux-DVB/DVICO/

Experimental Driver Test Results

  • Note: Apply this Patch to the xc-test branch for making it work with standard xc3028 firmware (xc3028-v27.fw) - otherwise the card will not be able tuning of non-Australian frequencies.
  • Successful tuning of typical German channels with standard xc3028 firmware and patched driver.
  • Successful tuning of typical Australian channels with stoth/v4l-dvb/

Note: If the card does not work ensure that 80 firmware images were loaded, if not see the firmware section above to get the correct version.
