The paper presents the Block Diagram and the Functional Description of the HSP50214B. The output mode and microprocessor was applicated based on the requirement of the 256QAM signal. The parameter of HSP50214B was configurated. The PDC configuration is Realized by using VHDL program by the logical deviceCPLD. The PDC configuration process indicates the general method of the HSP50214B application.
