Si5350/51-B
Factory-Programmable Any-Frequency CMOS Clock Generator
Description
Features
The Si5350/51 family of highly flexible, programmable
clock generators can be customized to generate up to
eight independent non-integer-related frequencies. The
devices have eight CMOS clock outputs offered in a
space saving 4x4 mm 20-QFN or lower cost three clock
output versions offered in a 10-MSOP package. Each
output has an independent MultiSynth™ fractional
divider that accepts a high-frequency reference from
one of the device’s internal PLLs and accurately divides
down the clock to generate unique, non-integer-related
frequencies from 2.5 kHz to 200 MHz. Any combination
of output frequencies can be generated by the device.
All clocks are generated with 0 ppm frequency
synthesis error, enabling the replacement of XOs and
PLL-based clocks while simplifying design and
minimizing cost. As an added feature, the Si5350/51
features an integrated VCXO which eliminates the need
for pullable crystals. The Si5350 features configurable
control pin options allowing the direct pin control of
frequency select, output enable, spread spectrum
enable and powerdown. Each output supports 1.8, 2.5,
or 3.3 V operation, eliminating the need for external
level translators in mixed-supply applications.
- Generates any frequency on any output
- 2.5 kHz to 200 MHz
- Exact clock synthesis: 0 ppm error
- Similar frequency flexibility as 8 independent PLLs
- Accepts crystal or external reference clock
- < 70 ps typical period jitter for any configuration
- Glitchless switching between output frequencies
- Integrated VCXO eliminates need for pullable
crystal
