Skyworks Solutions Inc SI5326C-C-GM, PLL Frequency Multiplier 4 3.63 V 36-Pin QFN

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.
