CMOS Manchester Encoder-Decoder

Features

Description

• This Circuit is Processed in Accordance to MIL-STD-

883 and is Fully Conformant Under the Provisions of

Paragraph 1.2.1.

The HD-6409/883 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 communication, and can be operated in

either of two modes. In the converter mode, the MED con-

verts 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 elimi-

nates 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 Manches-

ter code, the advantages of using Manchester code are eas-

ily realized in a serial data link.

• Converter or Repeater Mode

• Independent Manchester Encoder and Decoder

Operation

• Static to One Megabit/Sec Data Rate Guaranteed

• Low Bit Error Rate

• Digital PLL Clock Recovery

• On Chip Oscillator

• Low Operating Power: 50mW Typical at +5V

• Available in 20 Lead Dual-In-Line and 20 Pad LCC

Package

In the Repeater mode, the MED accepts Manchester code

input and reconstructs it with a recovered clock. This mini-

mizes 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.

PACKAGE

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.
