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 ...
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, ...
The SN65xxx family of positive emitter-coupled logic (PECL) buffers, translators, and splitters for clock and data management provide flexibility by operating at various power supplies of 2.5V, 3.3V, ...
