Skyworks Solutions, Inc. Clock Generators, PLLs, Frequency Synthesizers SI5391B-A14402-GM

The Si5391B-A14402-GM is an ultra-low jitter clock generator capable of synthesizing a wide range of frequencies up to 1 GHz across 12 differential clock outputs. It utilizes a combination of a wide-band PLL and proprietary MultiSynth fractional synthesizer technology, allowing for both integer and non-integer frequency generation. The device offers phase jitter performance as low as 69 fs RMS in precision calibration mode, making it suitable for high-speed applications such as 100G/200G/400G networks. This clock generator supports a variety of output formats, including LVDS, LVPECL, LVCMOS, CML, and HCSL, with programmable signal amplitudes. It features an input frequency range of 25 to 54 MHz for external crystals and 10 to 750 MHz for differential clocks. The output frequency range extends from 100 Hz to 1028 MHz for differential outputs and up to 250 MHz for LVCMOS outputs. Configuration is facilitated through ClockBuilderPro software, allowing for quick setup and customization. The Si5391B-A14402-GM operates within a temperature range of -40 to +85 ¬8C and comes in a compact 64-QFN package. Its ability to replace multiple clock ICs and oscillators with a single device makes it a versatile choice for various applications, including clock tree generation and FPGA clocking.
