MA1916 - Radiation Hard Reed-Solomon & Convolution Encoder

Datasheet Summary

Description

VDD and GND (Power and Ground) The MA1916 uses a single power supply of 5V ±10%.

CLK (Clock) This input supplies a clock signal to the RS encoder and the Test generator.

It requires a signal with a nominal 50% duty cycle running at twice the input data rate for the RS encoder.

MA1916 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).
