Si5332 Data Sheet 6/8/12-Output Any-Frequency Clock Generator KEY FEATURES Based on Skyworks proprietary MultiSynth flexible frequency synthesis technology, Any-Frequency 6/8/12-output the Si5332 generates any combination of output frequencies with excellent jitter perfor- programmable clock generators mance (190 fs rms). The device s highly flexible architecture enables a single device Offered in three different package sizes, to generate a wide range of integer and non-integer related frequencies on up to 12 supporting different combinations of output differential clock outputs with 0 ppm frequency synthesis error. The device offers multi- clocks and user configurable hardware ple banks of outputs that can each be tied to independent voltages, enabling usage in input pins mixed-supply applications. Further, the signal format of each clock output is user-config- 32-pin, up to 6 outputs urable. Given its frequency, format, and supply voltage flexibility, the Si5332 is ideally 40-pin, up to 8 outputs suited to replace multiple clock ICs and oscillators with a single device. 48-pin, up to 12 outputs The Si5332 is quickly and easily configured using ClockBuilder Pro software. Clock- MultiSynth technology enables any- Builder Pro assigns a custom part number for each unique configuration. Devices frequency synthesis on any output up to ordered with custom part numbers are factory-programmed free of charge, making it 250 MHz easy to get a custom clock uniquely tailored for each application. Using the Si5332 s I2C Highly configurable output path featuring a interface, the device may be user-configured at power-up or internally-configured NVM cross point mux programmed with new configuration using the ClockBuilder Pro Field Programmer. Up to three independent fractional synthesis output paths Up to five independent integer dividers Applications: Embedded 50 MHz crystal option Input frequency range: Servers, Storage, Search Acceleration Communications External crystal: 16 to 50 MHz Ethernet Switches, Routers Broadcast Video Differential clock: 10 to 250 MHz LVCMOS clock: 10 to 170 MHz Small Cells, Mobile Backhaul/Fronthaul Test and Measurement Output frequency range: Print Imaging Industrial, Embedded Computing Differential: 5 to 333.33 MHz LVCMOS: 5 to 170 MHz User-configurable clock output signal format per output: LVDS, LVPECL, HCSL, LVCMOS Multi-profile configuration support Temperature range: 40 to +85 C Down and center spread spectrum RoHS-6 compliant Si5332 Family Reference Manual Skyworks Solutions, Inc.
