Description

The Si5323 is a jitter-attenuating precision clock multiplier for high-speed

communication systems, including SONET OC-48/OC-192, Ethernet, and Fibre

Channel. The Si5323 accepts dual clock inputs ranging from 8 kHz to 707 MHz

and generates two equal frequency-multiplied clock outputs ranging from 8 kHz to

1050 MHz. The input clock frequency and clock multiplication ratio are selectable

from a table of popular SONET, Ethernet, and Fibre Channel rates. The Si5323 is

based on Silicon Laboratories' 3rd-generation DSPLL

technology, which

provides any-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 1.8, 2.5, or 3.3 V

supply, the Si5323 is ideal for providing clock multiplication and jitter attenuation in

high performance timing applications.
