HD-15530
March 1997
CMOS Manchester Encoder-Decoder
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-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鏗乪s it as well as decod-
ing 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 environmen-
tal control system driven from a single twisted pair cable of
鏗乥er optic cable throughout the building.
