SILICON LABS SI5317A-C-GM

The Si5317 is a flexible 1:1 jitter cleaning clock for high-performance applications that require jitter attenuation without clock multiplication. The Si5317 accepts a single clock input ranging from 1 to 711 MHz and generates two low jitter clock outputs at the same frequency. The clock frequency range and loop bandwidth are selectable from a simple look-up table. The Si5317 provides jitter attenuation on any frequency in a highly integrated PLL solution that eliminates the need for external VCXO and loop filter components. The DSPLL loop bandwidth is user selectable, providing jitter performance optimization at the application level.
