Factory-Programmable Any-Frequency CMOS Clock Generator
Description
The Si5350/51 are highly flexible, programmable clock
generators that can be customized to generate up to
eight independent non-integer-related frequencies. The
device has eight CMOS clock outputs offered in a space
saving 4 mm x 4 mm 20-QFN and a 24-QSOP package,
or three clock outputs 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 8 kHz to 133 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
powerdown. Each outputs supports 2.5 or 3.3 V
operation, eliminating the need for external level
translators in mixed-supply applications.
