Si5332 Automotive Grade Data Sheet
AEC-Q100 Qualified, 6/8-Output, Any-Frequency Clock Generator
Based on Silicon Labs' proprietary
MultiSynth
â„¢
flexible frequency synthesis technology,
the automotive grade Si5332 generates any combination of output frequencies with ex-
cellent jitter performance (190 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 8 differential 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-con-
figurable. 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
â„¢
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. Using the Si5332's I
2
C
interface, the device may be user-configured at power-up, or internal configuration NVM
programmed with new configuration using the ClockBuilder Pro Field Programmer.
