XRT8020 650 MHz High-Speed Clock Synthesize

The XRT8020 is a High-Speed Clock Synthesizer that provides a high frequency Low Voltage Differential Swing (LVDS) clock output, using a low frequency crystal or reference clock. The device produces clock signals up to 650 MHz by multiplying the output of a standard crystal (ranging from 20 to 40 MHz), and can generate from a clock signal input up to 80MHz. The device utilizes an analog phase locked loop that provides the clock multiplication function (8x, 16x or 32x), and when combined with the crystal frequency augments the output frequency. Also, the output can be divided by a factor of two allowing the XRT8020 to cover a wider frequency range.
