Low-voltage positive emitter-coupled logic
- Low-voltage positive emitter-coupled logic
Low-voltage positive emitter-coupled logic, or LVPECL, is a power optimized version of the Positive emitter-coupled logic (PECL) technology, requiring a positive 3.3V instead of 5V supply. LVPECL is a differential signaling system and mainly used in high speed and clock distribution circuits.
