Description

The Intersil HD-15531 is a high performance CMOS deviceintended to service the requirements of MIL-STD-1553 andsimilar Manchester II encoded, time division multiplexedserial data protocols. This LSI chip is divided into two sections,an Encoder and a Decoder. These sections operateindependently of each other, except for the master reset andword length functions. This HD-15531 circuit provides many of therequirements of MIL-STD-1553. The Encoder produces thesync pulse and the parity bit as well as the encoding of thedata bits. The Decoder recognizes the sync pulse and identifiesit as well as decoding the data bits and checking parity.The HD-15531 also surpasses the requirements of MILSTD-1553 by allowing the word length to be programmable(from 2 to 28 data bits). A frame consists of three bits forsync followed by the data word (2 to 28 data bits) followed byone bit of parity, thus, the frame length will vary from 6 to 32bit periods. This chip also allows selection of either even orodd parity for the Encoder and Decoder separately.This integrated circuit is fully guaranteed to support the1MHz data rate of MIL-STD-1553 over both temperature andvoltage. For high speed applications the 15531B will supporta 2.5 Megabit/sec data rate.The HD-15531 can also be used in many party line digitaldata communications applications, such as a local area networkor an environmental control system driven from a singletwisted pair of fiber optic cable throughout a building.
