MA1916 - Dynex

MA1916 Radiation Hard Reed-Solomon & Convolution Encoder

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. The rising edge of CLK is used to generate the internal CLKS signal which clocks d.

The purpose of the checksum is to allow error correction within the data block. One important feature of the Reed-Solomon algorithm is that it allows correction of a burst error which corrupts upto 1.
