HD4-6409-9 Datasheet | Intersil

Description The HD-6409 Manchester Encoder-Decoder (MED) is a high speed, low power device manufactured using self-aligned silicon gate technology. The device is intended for use in serial data munication, and can be operated in either of two modes. In the converter mode, the MED converts Non return-to-Zero code (NRZ) into Manchester code and decodes Manchester code into Nonreturn-to-Zero code. For serial data munication, Manchester code does not have some of the deficiencies inherent in Nonreturn-to-Zero code. For instance, use of the MED on a serial line eliminates DC ponents, provides clock recovery, and gives a relatively high degree of noise immunity. Because the MED converts the most monly used code (NRZ) to Manchester code, the advantages of using Manchester code are easily realized in a serial data link. In the Repeater mode, the MED accepts Manchester code input and reconstructs it with a recovered clock. This minimizes the effects of noise on a serial data link. A digital phase lock loop generates the recovered clock. A maximum data rate of 1MHz requires only 50m W of power. Manchester code is used in magnetic tape recording and in fiber optic munication, and generally is used where data accuracy is imperative. Because it frames blocks of data, the HD-6409 easily interfaces to protocol controllers.
