A differential sinusoidal signal pair is generated on an integrated circuit (IC). The differential sinusoidal signal pair is distributed to clock receiver circuits, which may be differential amplifiers. The clock receiver circuits receive the differential sinusoidal signal pair and convert the differential...http://www.google.com.hk/patents/US7135907?utm_source=gb-gplus-share專利 US7135907 - Clock signal distribution utilizing differential sinusoidal signal pair
