The any-requency, any-output Si534140 clock generators combine a wide-band PLL
with proprietary MultiSynthM fractional synthesizer technology to offer a versatile and
high performance clock generator platform. This highly fexible 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 jtter per-
formance 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 ProM for fast,
free, and easy factory pre programming or the Si5341/40 can be programmed via I2C
and SPI serial interfaces.
