PRECISION CLOCK JITTER ATTENUATOR
Features
Applications
Description
The Si5316 is a low jitter, precision jitter attenuator for high-speed
communication systems, including OC-48, OC-192, 10G Ethernet, and
10G Fibre Channel. The Si5316 accepts dual clock inputs in the 19, 38,
77, 155, 311, or 622 MHz frequency range and generates a jitter-
attenuated clock output at the same frequency. Within each of these clock
ranges, the device can be tuned approximately 15% higher than nominal
SONET/SDH frequencies, up to a maximum of 710 MHz in the 622 MHz
range. The Si5316 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
Si5316 is ideal for providing jitter attenuation in high performance timing
applications.
Fixed frequency jitter attenuator
with selectable clock ranges at
19, 38, 77, 155, 311, and
622 MHz (710 MHz max)
Support for SONET, 10GbE,
10GFC, and corresponding FEC
rates
