This paper describes the MPEG-2/DVB scrambler unit (DVB-SU) and VLSI chip developed for ETRI's conditional access system (CAS) for a digital broadcasting system. The DVB-SU is designed and implemented based on an ASIC, FPGAs and a DSP. The ASIC, compliant with the EP-DVB common scrambling specification, is a 128-pin MQFP type and operates with a 50 MHz system clock; it has features of flexible conditional access handling and interfaces with a commercial MPEG-2 multiplexer in compliance with the MPEG-2 system specification (ISO/IEC 13818). It has been integrated as a part of a conditional access sub-system for a digital broadcasting system and conforms so that it meets all the initial objectives and performance requirements
