HI-15530
September 2013
5V / 3.3V Manchester Encoder / Decoder
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 HI-15530 is fully compatible with either 5V or 3.3V logic
and transceivers.
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 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.

DESCRIPTION
A high output signals the receipt of a valid word
Shifts data into the encoder on a low to high transition
Output is high during receipt of data after identification of a Sync
Pulse and two valid Manchester data bits.
Received Data output in NRZ format
12x the data rate. Clock for the transition finder and synchronizer,
which generates the internal clock for the remainder of the decoder
A high input indicates the 1553 bus is in its negative state.
This pin must be held high when the Unipolar input is used
A high input indicates the 1553 bus is in the positive state.
This pin must be held low when the Unipolar input is used
Input for unipolar data to the transition finder. Must be held low when
Not in use
Provides the DECODER CLOCK divided by 12, synchronized by the
recovered serial data
A high on this pin occurs during the output of decoded data which
was preceded by a Command (or Status) synchronizing character. A
low output indicates a Data synchronizing character
A high applied to this pin during a DECODER SHIFT CLOCK rising
edge resets the bit counter
0V supply
A high on this pin clears the 2:1 counters in both Encoder and
Decoder and resets the divide-by-6 circuit
Provides ENCODER CLOCK divided by 6
An active low output intended to drive the zero or negative sense of
a MIL-STD-1553 Line Driver
A low inhibits the BIPOLAR ZERO OUT and BIPOLAR ONE OUT by
forcing them to inactive high states
An active low output intended to drive the one or positive sense on a
MIL-STD-1553 Line Driver
Accepts serial data at the rate of the ENCODER SHIFT CLOCK
A high on this pin initiates the encode cycle. (Subject to the
preceeding cycle being complete)
Actuates a Command Sync for an input high and a Data Sync for a
low
An active high output which enables the external source of serial
Data
Clock input at 2 times the Data rate, usually driven by ¸6 OUT
Input to the divide by 6 circuit. Normal frequency is Data rate x12
3.0 V to 5.5 V power supply pin
