PCIe interface chipsets

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:
| Vendor | Chipset | A/V decoder | DVB support | Associated Kernel Modules |
Comments |
|---|---|---|---|---|---|
| Conexant | CX23885/7/8 | ✔ Yes | ✔ Yes |

analog support is currently not universal (i.e. not implemented with all devices) |
| Conexant | CX25854/8 | ✔ Yes | ✘ No |

- ATI Theater 550/650/750
- 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/SAA7164 (multimedia A/V bridge) ... see Saa7162 devices for more info
- Some newer cards use FPGAs from Lattice or Altera.
Currently, only the CX23885 and SAA7162 IC families have published drivers from LinuxTV.
