KWorld 330U Employs Samsung S5H1409X01 Demodulator

KWorld 330U Employs Samsung S5H1409X01 Demodulator

[Robert Krakora]

Mauro:

The KWorld 330U employs the Samsung S5H1409X01 demodulator, not the
LGDT330X.  Hence the error initializing the LGDT330X in the current source
in em28xx-dvb.c.

Hello Robert,

Well, that's good to know.  I don't think anyone has done any work on
that device recently, so I don't know why the code has it as an
lgdt3303.

Do you know which tuner chip the device has?  The reason I ask is
because I'm working on another device that also has the s5h1409, and
it's got an xc3028L (the low power version of the xc3028).  If the
330U also has the xc3028L, then we need to make sure to indicate that
in the device profile so it doesn't burn out the chip.

We're probably also going to need to get a Windows trace, so we know
how to setup the s5h1409 configuration.

Devin

Devin:

I believe that it has the 3028 and not the 3028L as the part gets a little
toasty even on Windows,  I will get the magnifying glass out and look again
though (I am over 40 and becoming near-sighted).  I can get the Windows
trace using USBTrace on Windows XP or with my Elisys USB Analyzer.

Devin:

I took a stab at attaching the Samsung demod to the em28xx and got the
following error.  My guess is that the demod address is wrong.  How does one
go about dissecting vendor requests in a USB trace to obtain setup
information for this part?  I was going to put an I2C analyzer on the I2C
line while running Windows to capture I2C traffic.  I will get a Windows USB
trace tomorrow and e-mail it out.  Sure would be easier with the specs or a
little help from KWorld.  ;-)

I believe Douglas submitted this patch
(http://linuxtv.org/hg/v4l-dvb/rev/77f789d59de8) that got committed. 

I've been meaning to get back to this because the "A316" part of the
name caught my attention -- I do not recall having seen such a reference
made by KWorld, nor is it typical of their nomenclature style, rather,
it is entirely consistent with that used by AVerMedia

Hello Robert,

For getting a USB trace, I typically use SniffUSB:

http://www.pcausa.com/Utilities/UsbSnoop/default.htm

There could be several possibilities regarding the reason it doesn't
answer i2c requests.  The two most likely are that either
you have the wrong i2c address or you need the GPIOs to be setup
correctly because the s5h1409 is being held in reset (more likely).
Both of these can be determined from the USB trace.

If you send me the USB trace, I will take a look, and since I am
already working on a similar device I can compare the two traces.

Regards,

Devin

Sorry, that was a memory association thing --- I had originally looked
at the KWorld patch (Mauro, Dec 9) at the same time that I had with the
ever so slightly older, and topically similar, HVR-850 patch (Douglas,
Dec 8; see http://linuxtv.org/hg/v4l-dvb/rev/402de62fe6a6).

Mauro -- can you shed any light in regards the "A316" part of the name
descriptor ?

Sure, no problem.

Probably inherited from vendor/product ID, as follow:

em28xx-cards.c:

{ USB_DEVICE(0xeb1a, 0xa316), .driver_info = EM2883_BOARD_KWORLD_HYBRID_A316 },
                        ^^^

Ahh, very good.

Mauro, or whomever is going to end up spinning the patch incorporating
the correction regarding the demod. information, I suggest that the
descriptor "EM2883_BOARD_KWORLD_HYBRID_A316" be simultaneously changed
to "EM2883_BOARD_KWORLD_ATSC_330U" to reflect the device's more common name.

Douglas:

A316 is actually the product ID portion of the USB vendor/product IDs.  It
should be 330 instead of A316.

I created a skeleton page for the 330U (
http://www.linuxtv.org/wiki/index.php/KWorld_ATSC_330U ). Robert, if it
is possible, could you provide/upload any photos, and/or further info.
Thanks.

I agree with that. It should be replaced.
