Si5332 Data Sheet

6/8/12-Output Any-Frequency Clock Generator

Based on Silicon Labs proprietary MultiSynth™ flexible frequency synthesis technology,

the Si5332 generates any combination of output frequencies with excellent jitter perfor-

mance (230 fs rms). The device's highly flexible architecture enables a single device to

generate a wide range of integer and non-integer related frequencies on up to 12 differ-

ential clock outputs with 0 ppm frequency synthesis error. The device offers multiple

banks of outputs that can each be tied to independent voltages, enabling usage in

mixed-supply applications. Further, the signal format of each clock output is user-config-

urable. Given its frequency, format, and supply voltage flexibility, the Si5332 is ideally

suited to replace multiple clock ICs and oscillators with a single device.

The Si5332 is quickly and easily configured using ClockBuilder Pro™ software. Clock-

Builder Pro assigns a custom part number for each unique configuration. Devices

ordered with custom part numbers are factory-programmed free of charge, making it

easy to get a custom clock uniquely tailored for each application. Si5332 can also be

programmed via an I2C serial interface.
