Features

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 technology, which provides any-
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.
Not recommended for new
designs. For alternatives, see the
Si533x family of products.
