Highly Integrated Clock Generator for 10/25/100G
Si5332
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. This highly flexible architecture is capable of synthesizing a wide range of integer and non-integer related frequencies up to 312.5 MHz on up to 12 differential clock outputs while delivering sub-280 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. 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”.
Si5332 Any-Frequency Clock Generators
Industry’s Most Highly Integrated Clock Generator for 10/25/100G
The Si5332 Any-Frequency clock generator provides the highest level of integration available, enabling complete clock tree consolidation in 10/25/100G data center, communications, and industrial applications. With an output frequency range of up to 312.5MHz, the device features jitter performance of 230fs TYP, low power consumption (<300mA for 8 outputs), and is offered in 6/8/12-output options. Si5332 features proprietary MultiSynth divider technology, providing fractional clock synthesis with 0ppm accuracy on any output. The device also includes up to 7 user defined hardware input pins that can be assigned as output enable for one or more outputs, frequency control, spread spectrum enablement, or input reference selection. Si5332 can be quickly and easily configured using ClockBuilder Pro software, available in both factory pre-programmed as well as in-system programming options.
