METHOD AND DEVICE FOR HIGH-PERFORMANCE INTERCONNECTION BETWEEN INTERFACE CIRCUITS COUPLED WITH INFORMATION BUSES

摘要

PURPOSE: To provide a device and method for flexibly interconnecting information buses, and make multiple connections at the least cost by using many common components. ;CONSTITUTION: To interconnect 1st and 2nd information buses 26 and 48 having plural data lines respectively, a couple of unidirectional information paths consisting of twisted pair cables are provided together with a 25MHz strobe. Information is transferred by using dummy ECL signal level. A couple of clock differential receiver circuits are provided and data are transferred through an interconnection bus 46 by using both an upstream and a downstream end for a transfer clock signal and transferred from one bus to the other bus at a speed of 50MHz.;COPYRIGHT: (C)1994,JPO
