Abstract : The patent describes a multi-channel apparatus for error-free translation of asynchronous data channels into a serial data stream. Independent synchronizing circuitry at each channel performs bit timing recovery to allow incoming bits to be sampled and properly interpreted and also stores bits in a manner to absorb bit difference resulting from incoming data rate differences. Common synchronous timing circuitry provides control signals to transfer data synchronously out of a memory device, to prevent interference between asynchronous write and asynchronous read operations, and to multiplex the individual channel outputs in a serial data stream.
