The Fujitsu MB510 is an ultra high speed, two modulus prescaler that forms a Phase Locked Loop (PLL) when combined with a frequency synthesizer such as the Fujitsu MB87001A. It divides the input frequency by the modulus of 128/144 or 256/272, and operates at a low power supply current of 10mA at 5.0V. Through the use of Fujitsu's Advanced Process Technology, the MB510 achieves extremely small stray capacitance from its internal elements.
