Si5325A

Si5325A Jitter Attenuator Clock Multiplier

The Si5325A 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 1417 MHz. The Si5325A delivers 0.6 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.
