Si5332 Data Sheet
6/8/12-Output Any-Frequency Clock Generator
KEY FEATURES
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.
• Any-Frequency 6/8/12-output
programmable clock generators
• Offered in three different package sizes,
supporting different combinations of output
clocks and user configurable hardware
input pins
• 32-pin QFN, up to 6 outputs
• 40-pin QFN, up to 8 outputs
• 48-pin QFN, up to 12 outputs
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.
