Description
The Si5368 is a jitter-attenuating precision clock multiplier for
applications requiring sub 1 ps rms jitter performance. The
Si5368 accepts four clock inputs ranging from 2 kHz to
710 MHz and generates five independent, synchronous clock
outputs ranging from 2 kHz to 945 MHz and select
frequencies to 1.4 GHz. The device provides virtually any
frequency translation combination across this operating
range. The outputs are divided down separately from a
common source. The Si5368 input clock frequency and clock
multiplication ratio are programmable through an I
2
C or SPI
interface. The Si5368 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 or 2.5 V supply, the Si5368 is ideal for
providing clock multiplication and jitter attenuation in high
performance timing applications.
