HD-6409 Datasheet | Intersil

March 1997 CMOS Manchester Encoder-Decoder 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...
