Revision as of 19:34, 3 March 2016

A DVB-T/DVB-T2 or DVB-C PCIe card from TechnoTrend with integrated CI Slot. The card seems to be a OEM version of DVBSky T980C.

Features

  • CI-Slot
  • Belling Lee Connector (Cable or Antenna)
  • PCIe x1
  • Low power

Technical Details

Original Version

Version 2.0

  • PCIe Bridge : Conexant PCIe A/V Decoder CX23885-15Z
  • DVB-T2/C demodulator : Si2168-B40
  • DVB-T2/C tuner : Si2157-A30
  • CI chip: CICORE 1.0 (same as CIMaX SP2HF)
  • PCI ID 13c2:3013


Driver and more

There's an open source driver that's included in kernel 3.19. The same driver works for both version 1.0 and 2.0. It can be built for older kernels using the media_build. Firmware is required for Si2168 demod and Si2158 tuner. See the details from the DVBSky T980C page.

Note! The CI handling is broken in the driver for kernels 4.0-4.5. This is fixed in the current media_tree and in kernels starting from 4.6.
