Si5328C Jitter Attenuator Clock Multiplier

The Si5328C jitter attenuator combines third-generation DSPLL technology to enable any-frequency clock generation and jitter attenuation for applications requiring a high level of jitter performance. This device supports 2 input(s), 2 output(s) and has a maximum frequency output of 346 MHz. The Si5328C delivers 0.3 ps rms phase jitter performance with 0 ppm error. The loop filter is fully integrated on-chip, eliminating the risk of noise coupling associated with discrete solutions. Further, the jitter attenuation bandwidth is digitally programmable, providing jitter performance optimization at the application level.

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.
