Emitter Coupled Logic Signaling

The PECL (Positive ECL) IO standard is simpler to design with when compared with ECL because it referenced to +5V which is a common voltage supply. PECL has the same 800 mV swing as ECL. LVPECL is ...

Save valuable picoseconds using ECL-wired OR

Often, when you are designing with high-speed ECL (emitter-coupled logic), you have too little time between clock cycles to implement logic functions using gates between flip‑flops. In these cases, ...

A Digital Design Flow for Differential ECL High Speed Applications

This paper presents a digital design flow in order to design high performance differential Emitter Coupled Logic (ECL) circuits efficiently. The proposed flow is similar to the ordinary digital CMOS ...
