Description

The Si5322 is a low jitter, precision clock multiplier for high-speed

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

Fibre Channel. The Si5322 accepts dual clock inputs ranging from 19.44

to 707 MHz and generates two equal frequency-multiplied clock outputs

ranging from 19.44 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 Si5322 is based on Silicon

Laboratories' 3rd-generation DSPLL

frequency synthesis 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 Si5322 is ideal for providing clock multiplication in high

performance timing applications.
