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
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
rate 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.
