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).
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.
