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. Positive Emitter Coupled Logic, or PECL, is a further development of the emitter coupled logic (ECL) technology and requires a positive 5V supply instead of a negative -5V supply. ... The abbreviation PECL can refer to: PHP Extension and Application Repository, a technology used in web servers. ...
