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 MultiSynthfractional 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 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 Profor fast,
free, and easy factory pre-programming or the Si5341/40 can be programmed via I2C
and SPI serial interfaces.
Applications:
• Clock tree generation replacing XOs, buffers, signal format translators
• Any-frequency clock translation
• Clocking for FPGAs, processors, memory
• Ethernet switches/routers
• OTN framers/mappers/processors
• Test equipment and instrumentation
• Broadcast video
