The Silicon Labs Si531x/2x/6x/7x jitter attenuators generate any combination of output frequencies from any input frequency. Using the Silicon Labs third-generation DSPLL architecture they simplify your clock tree design by replacing multiple clocks and oscillators. Minimising your BOM count and complexity.
These Silicon SI5326 series are jitter-attenuating precision clock multipliers for applications requiring sub 1ps jitter performance. They can be used in a variety of applications such as Optical modules, wireless base stations, data converter clocking, xDSL, Test and measurement equipment, broadcast video and plenty more.
Features of SI5326 – • Generates from 2 kHz to 945MHz • Select frequency of 2 kHz to 710MHz • Jitter generation as low as 0.3ps rms (50 kHz – 80MHz) • Small size (6 x 6mm) • LOL, LOS, FOS alarm outputs • Dual clock outputs with selectable signal format • Dual clock inputs with manual or auto controlled hitless switch • I2C or SPI programmable.
The SI5326 also has a crystal oscillator built in & can use that function as a clock source for frequency synthesis. The device’s input clock frequency and clock multiplication ratio are programmable through an I2C or SPI interface. The SI5326 can also withstand temperatures from -40°C up to +85°C. Using the Silicon Labs third-generation DSPLL architecture they simplify your clock tree design by replacing multiple clocks and oscillators, minimising your BOM count and complexity.
