Si5316
PRECISION CLOCK JITTER ATTENUATOR
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-rate 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.
