March 1997

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 Intersil HD-15531/883 is a high performance CMOS

device intended to service the requirements of MIL-STD-

1553 and similar Manchester II encoded, time division multi-

plexed serial data protocols. This LSI chip is divided into two

sections, an Encoder and a Decoder. These sections oper-

ate independently of each other, except for the master reset

and word length functions. This circuit provides many of the

requirements of MIL-STD-1553. The Encoder produces the

sync pulse and the parity bit as well as the encoding of the

data bits. The Decoder recognizes the sync pulse and identi-

fies it as well as decoding the data bits and checking parity.

• Support of MIL-STD-1553

• Data Rate (15531B) . . . . . . . . . . . . . . . .2.5 Megabit/Sec

• Data Rate (15531). . . . . . . . . . . . . . . . .1.25 Megabit/Sec

• Variable Frame Length to 32-Bits

• Sync Identification and Lock-In

• Separate Manchester II Encode, Decode

• Low Operating Power . . . . . . . . . . . . . . . . . 50mW at 5V

The HD-15531/883 also surpasses the requirements of MIL-

STD-1553 by allowing the word length to be programmable

(from 2 to 28 data bits). A frame consists of three bits for

sync followed by the data word (2 to 28 data bits) followed by

one bit of parity, thus, the frame length will vary from 6 to 32

bit periods. This chip also allows selection of either even or

odd parity for the Encoder and Decoder separately.

This integrated circuit is fully guaranteed to support the

1MHz data rate of MIL-STD-1553 over both temperature and

voltage. For high speed applications the 15531B will support

a 2.5 Megabit/sec data rate.

The HD-15531/883 can also be used in many party line digi-

tal data communications applications, such as a local area

network or an environmental control system driven from a

single twisted pair or fiber optic cable throughout a building.
