Features  
Description  
• Support of MIL-STD-1553  
The Intersil HD-15531 is a high performance CMOS device  
intended to service the requirements of MIL-STD-1553 and  
similar Manchester II encoded, time division multiplexed  
serial data protocols. This LSI chip is divided into two sec-  
tions, an Encoder and a Decoder. These sections operate  
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.  
• 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 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 can also be used in many party line digital  
data communications applications, such as a local area net-  
work or an environmental control system driven from a single  
twisted pair of fiber optic cable throughout a building.
