View source for TechnoTrend TT-budget CT2-4500 CI

A [[DVB-T]]/[[DVB-T2]] or [[DVB-C]] [[PCIe|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===

* PCIe Bridge : [[Conexant]] PCIe A/V Decoder [[Conexant_CX23885/7/8|CX23885-15Z]]
* DVB-T2/C demodulator : [[Silicon_Labs_si2168|Si2168]]-A20
* DVB-T2/C tuner : [[Silicon_Labs_si2158|Si2158]]-A20
* CI chip: CIMaX SP2HF
* PCI ID 13c2:3013
<br/>

== Driver and more ==

There's an open source driver that's included in kernel 3.19. 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.
