CMOS Manchester Encoder-Decoder

Description

The HD-6409/883 Manchester Encoder-Decoder (MED) is a
high speed, low power device manufactured using self­aligned silicon gate technology. The device is intended for
use in serial data communication, and can be operated in
either of two modes. In the converter mode, the MED con­verts Nonreturn-to-Zero code (NRZ) into Manchester code
and decodes Manchester code into Nonreturn-to-Zero code.
For serial data communication, 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 components, provides clock recovery, and gives a
relatively high degree of noise immunity. Because the MED
converts the most commonly 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 50mW of power.

Manchester code is used in magnetic tape recording and in
fiber optic communication, and generally is used where data
accuracy is imperative. Because it frames blocks of data, the
HD-6409/883 easily interfaces to protocol controllers.
