similar Manchester II encoded, time division multiplexed, serial data protocols. The device is divided into
two independent sections, encoder and decoder, with a common master reset. The function of the encoder
section is to produce the sync pulse and parity bit, and encode the data bits. The decoder section recognizes
the sync pulse, decodes the data bits and checks for parity.
temperature and supply voltage ranges. The device interfaces with CMOS, TTL or N-Channel support
circuitry and operates from a standard 5 volt supply. The circuit can also be used in many party line digital
data communications applications where high reliability command and control signals are required. Using
Aeroflex transceivers products (4400 Series) the Bit Error Rates (BER) and Word Error Rates (WER) of
MIL-STD-1553 can be achieved (Refer to MIL-STD-1553 Multiplex Applications Handbook
"MIL-HDBK-1553").
