It should be 270MHz for SDI. Unless this is sample rate. The 27 MHz clock is the sample rate of the parallel 8/10 bit CCIR656 interface. This has to be serialized into a SDI stream. > It would be quite intersting as you could capture unencrypted non-lossy > versions of any program...

MPEG2 decoder: http://spanik.free.fr/sat/digiquest/AV711x_3_1.pdf Multimedia bridge: http://www.linuxdvb.tv/documentation/SAA7146A_1.pdf Both chips are connected by the CCIR656 interface. As there is no easy access to the pins of the AV7111 a potential serializer has to be connected to the SAA7146A. With http://www.national.com/ds/CL/CLC020.pdf is a one-chip solution available which requires only a few resistors and capacitors. The cost should be less than 50 EUR. There is also an evaluation board http://www.national.com/pf/CL/CLC020.html available which costs about 100 US$.
