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)
