Description

The Intersil HD-15530 is a high performance CMOS device

intended to service the requirements of MlL-STD-1553 and

similar Manchester II encoded, time division multiplexed

serial data protocols. This LSI chip is divided into two

sections, an Encoder and a Decoder. These sections

operate completely independent of each other, except for

the Master Reset functions.

This circuit meets many of the requirements of MIL-STD1553. 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 identifies it as well as decoding the data bits and checking parity.

This integrated circuit is fully guaranteed to support the

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

voltage. It interfaces with CMOS, TTL or N channel support

circuitry, and uses a standard 5V supply.

The HD-15530 can also be used in many party line digital

data communications applications, such as an environmental control system driven from a single twisted pair cable of

fiber optic cable throughout the building.
