I'm not sure that I'm using this mail list correctly? Apologies if I'm not.
I've de-lidded the MPC718 card and the chip set is as below.
Devices
-------
Connexant CX23418 MPEG 2 Encoder
Zarlink MT352/CG COFDM Demodulator
XCeive 3028 Hybrid Tuner + analog demodulator
Hynix HY5DU283333B DDR RAM
Cirrus(?) 5340 CZZ Audio A->D
Crystals
---------
32 M : For Xceive xc3028
20.480 M : For Zarlink MT352
28.6363 : Not sure what this is for, the cx?

If you need me to do this run? Please just point me to correct files to edit and unix commands,
and I'll either run it manually or script it (perl, sed .... or whatever is needed etc)

It fizzled. There's an entry in the cx18 driver for the Yuan MPC718,
but it is incomplete. Here's what I think I can do:
1. Fix the analog basedband part (CVBS, S-Video) of the card based on
the windows *.inf file.
2. Get analog tuning working based on knowing the card has an XCeive
XC3028 anlog/digital tuner. For this I need someone to figure out for
certain what GPIO pin is used to reset the XC3028. This will require
someone with patience as the brute force search may require up to 32
loads/unloads/recompiles of the driver.
3. I might be able to get DVB-T working, but will need to rely heavily
on someone with the hardware and access to DVB-T. Here's how things
will go:
a. Someone really needs to figure out what DVB-T demodulator is on the
MPC718. It's housed in the metal can. :( The Yuan PG718 looks like a
PCI version of the MPC718, so maybe if someone can provide a list of the
chips on that card, it'll be the same. The Yuan MPC788 is reported to
use an XCeive XC3028 with an Intel/Zarlink CE6353/ZL10353 - so I can use
that as a first guess.
b. I need to know the crystal freq used with the demod. If it's the
Zarlink 10353 or equivalent, I'm betting it's a 20.48 MHz crystal.
Visual confirmation would be nice.
c. I need to know the I2C address of the digital demodulator. If it's
the Zarlink 10353 or equivalent, I'm guessing it's at 0x1e as most
Zl10353 eval kits used this apparently. If not, there's a way to use
the i2c-dev module and the i2c-detect tool (lm-sensors package) to try
and figure it out.
d. I need to know if the MPC718 uses a Parallel or Serial TS. This will
require module loads/unloads/recompiles of the driver. Hopefully this
will be an experiment that has to be run only once or twice.
So,
1. How bad do you want it to work?
2. Do you have a technical contact at Yuan?
;)

Andy
