Sub-nanosecond ECL uncommitted cell array for transmission system applications

Abstract

The paper describes the design and testing of a sub-nanosecond uncommitted cell array manufactured in BTRL ECL technology for transmission system applications. The array features a logic complexity of 64 D-type bistables, temperature-compensated bias and reference generators, and two levels of metal interconnect in CuAluSil. A 16-stage shift register, configured as a LAN interface circuit, has been implemented on the array and operated error-free at up to 328 Mbit/s, with sub-nanosecond rise and fall times, while dissipating 4.5 W.
