The PI6C3991JE is a clock generator, PLL, and frequency synthesizer chip designed and manufactured by Plessey Semiconductors. The device is designed to provide high-frequency clock and data signals from a single clock source to multiple devices, as well as synthesize signals from multiple frequencies. The operating frequency range is from 16 KHz to 1 GHz. Depending on the application, the device can generate either a single clock output, multiple independent clock outputs, or one or more quadrature signals.

When the PI6C3991JE is used for clock generation, it will accept an input frequency ranging from 1 KHz to 1 GHz. The output clock signal is then generated from this input frequency by dividing the frequency by a programmable division rate. The clock output is then available in two differential outputs, as well as one complimentary single-ended output.

When the PI6C3991JE is used as a frequency synthesizer, it will accept multiple input frequencies, ranging from 16 KHz to 1 GHz. It can then synthesize a new frequency by multiplying these input frequencies, with adjustable division and multiplication factors. The output frequency is again available in two differential outputs, as well as one complimentary single-ended output.

The PI6C3991JE is used for a variety of different applications, including clock generation and frequency synthesization for cellular base stations, DVD players, GPS satellite receivers, set-top boxes, and data communications equipment. Its wide operating frequency range, programmable division and multiplication factors, and low power consumption make it ideal for these applications.

In summary, the PI6C3991JE is a device designed by Plessey Semiconductors that can be used as a clock generator, PLL, and frequency synthesizer. It can operate over a wide range of frequencies and is used in a variety of applications. Its programmable division and multiplication factors, as well as its low power consumption, make it an ideal solution for many different applications.
