SI5341集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

Low-Jitter, 10 or 4-Output, Any-Frequency, Any-Output Clock Generator

The any-frequency, any-output Si5341/40 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 1 GHz on 10 differential clock outputs while delivering sub-100 fs rms phase jitter performance with 0 ppm error. Each of the clock outputs can be assigned its own format and output voltage enabling the Si5341/40 to replace multiple clock ICs and oscillators with a single device making it a true clock tree on a chip.
