Clock Clock Hitless Switching
Hitless Switching Si5364 provides reference monitoring clock switching that support Stratum 2/3/3E requirements. Clock switching automatic manually controlled. Small Size These devices provide space savings compared traditional solutions using discretely implemented PLLs clock modules. Proprietary DSPLL Technology within these devices utilizes digital signal processing provide superior jitter performance while keeping loop filter circuitry internal device. This level integration makes less susceptible board level noise, improving jitter performance.
