Si5332A-GM3 Low Jitter Clock Generator with 12 Outputs and Integer and Fractional Frequency Synthesis Modes

The Si5332A-GM3 any-frequency clock generator provides the highest level of integration available, enabling complete clock tree consolidation in 10/25/40/100G data center communications and industrial applications. With an output frequency range of 5 - 333.33, the device features both MultiSynth fractional as well as integer dividers, jitter performance of 0.190ps TYP, low power consumption and has 12 outputs. The Si5332A-GM3 also includes up to 5 user-defined hardware input pins that can be assigned as output enable for one or more outputs, frequency control, spread spectrum enablement, or input reference selection. Si5332A-GM3 can be quickly and easily configured using ClockBuilder Pro software, offering both factory pre-programmed as well as in-system programming options.

ClockBuilder Pro Field Programmer

When used with ClockBuilder Pro software, the ClockBuilder Pro Field Programmer makes it simple for systems designers to develop, program, and debug any Si5332/8, Si5350/1/6/7, Si534x/6x/8x/9x, Si540x, and Si55xx part families clock device “in-system,” or in one of the convenient QFN sockets. The field programmer supports I2C or SPI interfaces to the host system, and SPI to the field programmer's QFN socket boards.
