MA1916

Radiation Hard Reed-Solomon

& Convolution Encoder

Replaces June 1999 version, DS3590-4.0

DS3590-5.0 January 2000

The purpose of the MA1916 is to encode serial data to

allow error correction when the data is transmitted over a noisy

communication link. As the name suggests, the unit contains

two encoding elements. The Reed-Solomon encoder appends

a checksum to a block of data, guarding against burst errors in

a message. The convolution encoder continuously creates two

code bits for each data bit it receives, increasing the noise

immunity by doubling the band width of the message. The unit

also contains a test pattern generator which can be connected

to check the functionality of the RS encoder and to provide a

message timing signal (SMC_OUT).

FEATURES

■ Radiation Hard CMOS-SOS Technology

■ Low Power Consumption

■ Latch-up Free

■ High SEU Immunity

■ CCSDS Standard RS (255, 223)

■ Selectable Interleave Depths of 1, 4 or 5

■ 5MBit/sec Input Data Rate

Protection against a long error-burst can be increased by

interleaving a number of message packets passing through

the RS encoder. The MA1916 provides pin selectable

interleave depths of 1, 4 or 5. Interleave depths of greater than

5 do not significantly improve performance.

The MA1916 is designed to conform to the CCSDS

standard for telemetry 101.0.B.2. It is manufactured in a

radiation hard low power CMOS technology. This makes it

ideal for use in satellite communications systems. The encoder

reduces the risk of data corruption and allows the designer to

minimize the transmitter power needed to establish an

effective communications link.
