Abstract

A data receiver interface circuit is provided with a circuit for accepting correctly framed data. The plurality of data bits sandwiched between a pair of frame pulses is temporarily stored while the number of clock cycles occurring between the frame pulses is determined to be a valid number. The data is accepted by the receiver if the number of clock cycles occurring between the pair of successive frame pulses is a valid number.
