In relation to V4L-DVB devices, a PCIe interface chipset is a bridge between the device's receiver (in the case of TV tuner devices) and A/V inputs (in the case of some devices) and the host computer's PCIe "bus" (which really isn't a traditional bus, but rather a point to point serial connect lane(s)). Some examples of PCIe interface chipsets that are used in V4L-DVB PCIe cards include:

PCIe interface Chipsets
Vendor Chipset A/V decoder DVB support Associated
Kernel Modules
Conexant CX23885/7/8 Yes Yes
  • cx23885
analog support is currently not universal (i.e. not implemented with all devices)
Conexant CX25858 Yes No
  • cx25858
  • ATI Theater 550
  • ATI Theater 650
  • ATI Theater 750
  • Micronas APB 7202A nGene dual-channel PCI-Express multimedia controller ... see NGene devices for development info
  • Philips/NXP SAA7162 (dual A/V decoder) and SAA7160/SAA7161 (multimedia A/V bridge) ... see Saa7162 devices for more info
  • NXP SAA7164

Currently, only the CX23885 and SAA7162 IC families have published drivers from LinuxTV.
