Si5315A

Si5315A Jitter Attenuator Clock Multiplier

The Si5315A 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 644 MHz. The Si5315A delivers 0.23 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.

si5315-evb

Si5315 Any-Frequency Precision Clock Multiplier / Jitter Attenuator Evaluation Kit

The Si5315 precision clock accepts dual clock inputs ranging from 8 kHz to 644 MHz and generates dual clock outputs ranging from 8 kHz to 644 MHz. The Si5315 precision clock is based on our 3rd-generation DSPLL® technology, which provides any-rate frequency synthesis in a highly integrated PLL solution that eliminates the need for external VCXO and loop filter components. The Si5315 is ideal for SyncE applications.
