80 ps 30000 gates ECL gate array E-30000VH

摘要

The E-30000VH ECL (emitter-coupled-logic) gate array, which has a gate speed (with no load) of 80 ps and 30000 equivalent gates, is discussed. The E-30000VH features a three-level series gate circuit, a preimplemented clock distribution net of 150-ps skew, and 300 signal I/Os. The chip structure, internal gate circuit, and package are described. The results of gate speed measurements, using a ring oscillator, are reported.
