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 …
WebLVPECL tends to be a little less power efficient than LVDS due to its ECL origins and larger swings, however it can also operate at frequencies up to 10 Gbps because of its ECL characteristics. LVPECL output currents are typically 15mA, and this is derived from an open emitter. This requires termination into a resistive
