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

- Si5350 (pin) and Si5351 (I C) versions

- User-definable control pins:

- Frequency select, output enable, spread spectrum

enable, powerdown

- Spread spectrum clock generation

- –0.1 to –2.5% down, ±0.1 to ±1.5% center

- Two week sample lead time for any custom clock

- Small size: 4x4 mm 20-QFN and 10-MSOP

- Industrial temperature range: –40 to +85
