Low Jitter Clock Generators

The any-frequency, any-output Si5332 clock generators combine a wide-band PLL with proprietary MultiSynth fractional synthesizer technology to offer a versatile and high performance clock generator platform. Si5332 features an embedded reference crystal option, providing further integration and simplifying board design. This highly flexible architecture is capable of synthesizing a wide range of integer and non-integer related frequencies up to 333.33 MHz on up to 12 differential clock outputs while delivering sub-200 fs rms phase jitter performance with 0 ppm error. The device includes two independent spread spectrum modulation domains, an I2C interface for in-system programming, and user-defind hardware input pins that can be assigned during configuration development as output enable, frequency control, input selection, or spread spectrum enablement. The multi-profile feature provides the ability to store up to 16 unique configuration files in the same orderable part number, using the hardware input pins to select between each configuration. Each of the clock outputs can be assigned its own format, enabling the Si5332 to replace multiple oscillators, buffers, and/or clock generators with a single device making it a true “clock tree on a chip”.
