GENERAL DESCRIPTION
The HI-15530 is a high performance CMOS integrated
circuit designed to meet the requirements of Mil-Std-1553
and similar Manchester II encoded, time division
multiplexed serial data protocols. The HI-15530 contains
both an Encoder and Decoder, which operate
independently.
The device generates Mil-Std-1553 sync pulses, parity bits
as well as the Manchester II encoding of the data bits. The
decoder recognizes and identifies sync pulses, decodes
data bits, and performs parity checking.
The HI-15530 supports the 1Mbit/s data rate of Mil-Std-
1553 over the full temperature and voltage range.
For applications requiring small footprints and low cost, the
HI-15530 is available in a 24-pin plastic SOIC package.
Ceramic DIP and LCC packages are also available to
achieve the highest level of reliability and to provide drop-in
replacement for obsolete parts from other manufacturers.
