Description

Emitter-coupled logic (ECL) including positive ECL (PECL) and low-voltage PECL (LVPECL)) interfacing often the first solution considered when a high-speed interface is needed suffers from high power consumption. TIA/EIA-644 low voltage differential signaling (LVDS) provides a low-power alternative to ECL when selecting a high-speed interface solution. This paper compares the power consumption o
