ABSTRACT:
An elastic buffer for absorbing frequency jitter or drift of an incoming data signal which includes a serial stack of data register. These data registers are used for storing data bits from an incoming data stream one at a time with each bit adjacent a next earlier bit at a frequency equal to the frequency of the incoming data and also for releasing stored bits onto an output data line. The stored bits are released one at a time at a predetermined fixed rate equal to the average frequency of incoming data from a number of registers away from the register into which data is being written which depends on the frequency difference between incoming data and the fixed rate aforesaid.
