    LV-PECLlLow Voltage PosiTlve Emitter-Couple Logic， That is to say, the low-voltage positive emitter coupling logic, using a 3.3V or 2.5V power supply, LV-PECL differential oscillator is evolved from PECL. PECL stands for PosiTve Emitter Couple Logic, which means positive emitter coupled logic and uses a 5.0V power supply PECL evolved from ECL, which is Emitter Couple Logic, also known as emitter coupled logic. This circuit is a type of unsaturated digital logic circuit where the transistor operates in the linear or cutoff region, and its speed is not limited by the storage time of minority carriers. Therefore, it is one of the fastest logic circuits available, capable of operating at a rate of up to 10Gbps. ECL has two power supply voltages VCC and VEE. When VEE is grounded and VCC is connected to positive voltage, the logic at this time is called PECL; When the VCC is grounded and the VEE is connected to a negative voltage, the logic becomes NECL, and the VEE is generally connected to a -5.2V power supply; The narrow definition of ECL generally refers to NECL. Due to the fact that PECL/LVPECL can share a positive power supply with other circuits in the system, PECL/LV-PECL is more widely used compared to ECL. At first, PECL devices were connected to VCC at+5V. Later, in order to directly utilize the widely used 3.3V and 2.5V voltages, LVPECL (Low Voltage PECL) with VCC=3.3V/2.5V emerged
