[mythtv-users] Compro VideoMate T-750

[Rod]

    Hi, has anyone had any experiance with the above Video card?

    Here is what I have found on this little card....

    The RTC on the card, being a known chip, also linked into the 
"Power-SW" wiring from the front panel simplifies the "power saving 
feature, also the complexity across differing mobo's and their BIOS 
timing circuits

    Onboard, it has the following devices.

    DVB-in -> QT1010 -> CE6353 -> SAA7135
    Analog-in -> XC2028 -> SAA7135
    Composite-in -> SAA7135
    Radio-in -> SAA7135
    RTC (DS1337)-> SAA7135 (I2C)
    EEPROM -> SAA7135 (I2C)

    I have QT1010, SAA7133/5, XC2028, DS1337 loaded as a modules

    The RTC is connected to the I2C buss from the SAA7135, the INT 
output is connected thru a custom driver chip (seems like just a custom 
driver similar to a ULN2004 driver chip, I doubt its I2C, it wouldn't 
buzz out to that chip

       I2C addresses
    QT1010    =    0xA0    DVB Front End
    DS1337   =    0xD0     RTC, the Alarm out restarts the computer (I 
think)
    XC2028   =    0x         Analog/Radio front End (Difficult to get 
address info)
    CE6353   =   0x1E        Nordig Unified DVB-T CDFDM Terrestrial 
Demodulator

    QT1010 (module)
    DS1337 (module)
    XC2028 (CX8800 = module)  or CX88...  series modules
    CE6353   not sure of the module for this yet... not sure how 
programmable it is


    Have a PDF of the QT1010, cannot find the linky again

    CE6353 looks pin-for-pin compatable for the following (Zarlink Devices)

    Also the I2C address on the chip Doc refers to SADD0:4, in the doc, 
it said that "In the current TNIM evaluation application, the 2-wire bus 
address is 0001 111 R/ W with the pins connected as
follows:"
   
    For the T-750 the configuration is 0001 111r/w   Strange how they 
didn't change it, but thats what happens when you follow App notes,...

    So, I hope this helps someone getting these little beasties going, I 
would love to utilise them ;o)
