In the typical PECL 100K logic output Voh is 2.35 volts and Vol is 1.60 volts at 3.3 Vcc. The center voltage of the PECL is therefore1.975 volts.
If a 50 ohmresistor is placed between the output and Vcc – 2 volts (1.3 volts), the current through the resistor is (1.975 – 1.3) / 50 = 13.5 mA.
The same load can be simulated by a resistor of 147 ± 1% ohms to ground (1.975 / 0.0135 = 146.29 ohms). If additional load current is placed
on the output, its load current must be subtracted fromthe 13.5 mA to calculate a new load resistor. Using simlar calculations, use 274 ± 1%
ohms to ground for 5.0V operation.
