Data Interface Circuit

An integrated circuit comprising:

• a space switch configured to route received data to an output, the output selected from a plurality of outputs;
• a plurality of input interfaces configured to receive input data, each input interface comprising an input voltage level shifter and an input distributed first-in first-out (FIFO) element interconnected by segments of interconnects, wherein the input voltage level shifter is configured to convert a voltage level of the input data to a voltage level compatible for the space switch, and wherein the input distributed FIFO element is configured to convert a frequency of the input data to a frequency compatible for the space switch;
• and
• an output interface configured to receive routed data from the space switch and to provide output data to the selected output, the output interface comprising an output voltage shifter coupled in series to an output distributed FIFO element, wherein the output voltage shifter is configured to convert a voltage level of the routed data to a voltage level compatible for the selected output, and wherein the output distributed FIFO element is configured to convert a frequency of the routed data to a frequency compatible for the selected output.

A method comprising:

• receiving data samples in a first sequential order, the data samples having a voltage level and a frequency;
• selecting an output from a plurality of outputs, wherein the selected output has requirements for a voltage level and a frequency different from the received data samples;
• routing the data samples to the selected output;
• converting the voltage level of the data samples to an output voltage level compatible for the selected output;
• converting the frequency of the data samples to an output frequency compatible for the selected output;
• and
• reordering the data samples from a first sequential order to a second sequential order compatible for the selected output.
