SILICON LABS SI5341A-B04700-GM

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." The Si5341/40 can be quickly and easily configured using ClockBuilderPro software. Custom part numbers are automatically assigned using a ClockBuilder Pro for fast, free, and easy factory pre-programming or the Si5341/40 can be programmed via I²C and SPI serial interfaces. The Si5340/41-D combines a wide band PLL with next generation MultiSynth technology to offer the industry's most versatile and high performance clock generator. The PLL locks to either an external crystal between XA/XB or to an external clock connected to XA/XB or IN0, 1, 2. A fractional or integer multiplier takes the selected input clock or cystal frequency up to a very high frequency that is then divided by the MultiSynth output stage to any frequency in the range of 100 Hz to 1 GHz on each output. The MultiSynth stage can divide by both integer and fractional values. The high-resolution fractional MultiSynth dividers enable true any-frequency input to any-frequency on any of the outputs.
