Its basically just a custom Lattice CPLD wired nearly directly to the PCMCIA interface. This is so IO and attribute memory can be accessed on the card. There are also some latches to demultiplex the address/data lines from the DEBI bus as well, but you don't program them; it just happens automatically during a DEBI access. Everything is wired to the 8 bit DEBI expansion bus on the SAA7146. About the cheapest way you could possibly do it... Whats on the KNC1/Typhoon/Terratec? Do they have a more sophisticated chip (e.g. the CiMAX 2.0 chip).... if they do, they could certainly use the generic dvb_ca_en50221 implementation to do most of the work. -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
