HI-15530
October 2008
5V / 3.3V Manchester Encoder / Decoder
GENERALDESCRIPTION
FEATURES
! MIL-STD-1553 compatible
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.
! 5V or 3.3V operation
! Interfaces to HI-1567 Transceiver Family
! Small footprint 24-pin plastic SSOP package
option
The HI-15530 is fully compatible with either 5V or 3.3V logic
and transceivers.
! Direct replacement for:
Harris/Intersil HD15530
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.
GEC Plessey Semiconductors MAS15530
Aeroflex ACT15530
The HI-15530 supports the 1Mbit/s data rate of MIL-STD-
1553 over the full temperature and voltage range.
! 1.25 Mbit/s Maximum Data Rate
! Manchester II Encode and Decode
! Sync identification and Lock-in
For applications requiring small footprints and low cost, the
HI-15530 is available in a 24-pin plastic SSOP package.
Ceramic DIP and LCC packages are also available to
achieve the highest level of reliability and to provide drop-in
replacements for obsolete parts from other manufacturers.
