Features
Applications
Description
The Si5366 is a jitter-attenuating precision clock multiplier for high-speed
communication systems, including SONET OC-48/OC-192, Ethernet, and
Fibre Channel. The Si5366 accepts four clock inputs ranging from 8 kHz
to 707 MHz and generates five 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 frequencies. The Si5366 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 Si5366 is ideal for
providing clock multiplication and jitter attenuation in high performance
timing applications.
