Title :
DMA 2280 and DMA 2285: processing of D2, D, C-MAC signals and descrambling
Author_Institution :
ITT Intermetall, Freiburg, West Germany
Abstract :
The DMA 2285 is a digital real-time descrambling processor for both the D2-MAC and the D-MAC/packet system. Together with the appropriate D2- or D-MAC/Packet decoder chip 2280, it can be used to build up a D2- or D-MAC/Packet conditional access receiver. The programmable VLSI circuits in CMOS technology are housed in 68-pin PLCC packages and contain on a single silicon chip extensive functions
