LVPECL terminology explanation and principle application



LVPECL - Low Voltage Positive Emission Coupled Logic. Compared to typical CMOS oscillators, LVPECL products have faster rise/fall times and less noise interference, making them more suitable for applications with high sensitivity to interference noise (clock and signal transmission).
Advantages of LVPECL output:
1. Able to drive long-distance power lines.
2. Ideal application in high-speed circuits.
3. Due to the high voltage swing, it has excellent jitter performance.
Disadvantages of LVPECL output:
1. Incompatible 1.8V power supply.
2. Due to the high power consumption of differential output and external DC bias, single ended output is preferred.
