CX2388x + Xceive XC2028/3028 tuner

GNU Radio
1

Hello,

I’m sorry to bother with this question, but I don’t have the necessary
technical knowledge to answer it. A couple years ago a module for the
CX2388x video processor so it could work as an ADC for GNU Radio feeding
raw data.

I have a TV card with that chip but the tuner is a Xceive XC2028.

This tuner is programmable via firmware. There is support for it in the
Linux kernel since 2.6.25. Firmware images are 22 bytes long and are
stored in a single file; there are like 80 images, some of them with
suggestive names like:

Firmware 79, type: SCODE FW HAS IF (0x60000000), IF = 8.20 MHz id:
(0000000000000000)

I was wondering if it’s at least theoretically possible to program this
tuner to output an IF instead of a TV composite signal.

Thank you

Hi Carlos,

According to the product brief at
http://www.xceive.com/technology_XC2028.htm
it has a SIF output, but without the complete
datasheet, it is hard to say.

You could probably check out with the authors of linux
XC2028 tuner driver. Their contact are listed in the
tuner-xc2028.c source code. The source can be obtained
from www.kernel.org

Regards,
Hew
