HIGH SPEED INTERFACE APPARATUS

摘要

PURPOSE: The apparatus realizes the high speed by doubling the bandwidth as maintaining bus width and system bus frequency. CONSTITUTION: The apparatus comprises: a data driving part(100) outputting 4 level data signal after decoding 2 bits data signal respectively; a reference potential generating part(200) generating a reference potential of 3 level to judge the potential level of the 4 level data signal; and a receiver part(300) outputting 2 bits data signal by encoding a signal outputted by comparing the 4 level data signal and the reference potential signal of 3 level.
