WebLVPECL is evolved from PECL. PECL is Positive Emitter-Couple Logic, which is positive emitter coupling logic. Meaning, using 5.0V power supply, and PECL is evolved from ECL, ECL is Emitter-Couple Logic, which is the emitter coupling logic, ECL has two supply voltages VCC and VEE. When VEE is grounded and VCC is connected to a positive … WebIn electronics, emitter-coupled logic (ECL) is a high-speed integrated circuit bipolar transistor logic family.ECL uses an overdriven bipolar junction transistor (BJT) differential amplifier with single-ended input and limited …
