The Si5328 is a jitter-attenuating precision clock multiplier for  
Synchronous Ethernet applications requiring sub 1 ps jitter performance  
and ultra-low loop bandwidth. When combined with a low-wander, low-  
jitter reference oscillator, the Si5328 meets all of the wander, MTIE,  
TDEV, and other requirements listed in ITU-T G.8262/Y.1362. The Si5328  
accepts two input clocks ranging from 8 kHz to 710 MHz and generates  
two output clocks ranging from 8 kHz to 808 MHz. The two outputs are  
divided down separately from a common source. The Si5328 can also  
use the TCXO as a clock source for frequency synthesis. The device  
provides virtually any frequency translation combination across this  
operating range. The Si5328 input clock frequency and clock

2
multiplication ratio are programmable through an I C or SPI interface. The  
®
Si5328 is based on Silicon Laboratories' third-generation DSPLL  
technology, which provides frequency synthesis and jitter attenuation in a  
highly integrated PLL solution that eliminates the need for external VCXO  
and loop filter components. The DSPLL loop bandwidth is digitally  
programmable, providing jitter performance optimization at the application  
level. Operating from a single 2.5 or 3.3 V supply, the Si5328 is ideal for  
providing clock multiplication and jitter attenuation in high-performance,  
Synchronous Ethernet timing applications.
