ABSTRACT:
A circuit for converting a multi-bit data signal from a first format to a second format. The circuit includes an input for receiving the multi-bit data signal in a first format, an output for providing the multi-bit data signal in a second format, and a ring counter having a number of stages for providing, in sequential order, stage output signals. A format conversion device connected between the input and the output has a number of latches with each latch being connected to the input for simultaneously receiving data bits of the multi-bit data signal in the first format. A control circuit is provided for controlling the latching of selected data bits in each of the latches, and a transmission circuit is provided between the latches and the output for transmitting the bits latched in the latches to the output responsive to the stage output signals of the ring counter, thereby placing the multi-bit data signal in the second format.
