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 712.5 MHz on 10 differential clock outputs while delivering sub-150 fs rms phase jitter performance and 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 in a chip”. The Si5341/40 can be quickly and easily configured using ClockBuilder Pro software. Custom part numbers are automatically assigned using a ClockBuilder Pro for fast, free, and easy factory programming, or the Si5341/40 can be programmed in-circuit via I²C and SPI serial interface.
