Si5350/51

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 enable and

powerdown. Each outputs supports 2.5 or 3.3 V

operation, eliminating the need for external level

translators in mixed-supply applications.
