This paper describes the MPEG-2/DVB Scrambler Unit(DVB-SU) developed for the ETRI's Conditional Access System(CAS) of Digital Broadcasting System. The DVB-SU is designed and implemented based on an ASIC, FPGAs and a DSP. The ASIC, compliant with EP-DVB common scrambling specification, is 128-pin MQFP type and operated in 50 MHz system clock. It has features of flexible conditional access handling and compatibility with MPEG-2 multiplexer(1S 138 18-1). It had been integrated as a part of Conditional Access System and conformed that it met all initial objectives and performance requirements
