摘要: Apparatus for providing automatic clock de-skewing a plurality of circuit boards data processing system. In preferred embodiment, each board is multi-layer construction and contains distribution chip which includes on-chip circuitry de-skewed clocks to other chips on the board. implementation circuitry, feedback including multi-tapped delay line an accurate reference are employed in conjunction with phase comparator automatically at outputs chip. The advantageously provided by strip transmission formed conductive layer containing chips.
