Sabrent TV-PCIRC

Introduction

Lots of Chinese supplies making piles of $20 crap.

This page is specific to Sabrent PCI TV Tuner Card 7130/TV-PCIRC01061000290

If you have a different model of Sabrent TV-PCIRC card - well, good luck. They rebadged pretty much anyone's overstock tuner card, so buyer beware.

I just want it to work under Linux!

Use the audio-pass through cable. The remote control doesn't work, but the card tunes NTSC.

modprobe saa7134 card=86 tuner=32

Things on The Card

Encoder/PCI Bridge

Clearly labelled, it's a Philips SAA7130HL.

Tuner

If you peel away (carefully!) the OEM label, the can has a sticker that says:

  SAMSUNG
TCPN9082DC270(T)
- - - - - - - -
030527    AIO

The tuner is on i2C bus address 0x60 (which is a pretty standard place for the tuner to be)

Crystals

One 4.000 and one 32.110

The Mystery Chip
