Si5395A High-Performance Clock Jitter Attenuator, Jitter Cleaner

The Si5395A 12 -output, ultra-high-performance jitter attenuator combines fourth-generation DSPLL and MultiSynth technologies to enable any-frequency clock generation and jitter attenuation for applications like 56G PAM4 SerDes requiring the highest level of jitter performance. The device has an ultra-low jitter of 69 fs and a frequency output range up to 1028 MHz and delivers a 0.09 ps rms phase jitter performance with a 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. The Si5395A can be quickly and easily configured using ClockBuilder Pro software.

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.
