Description
The Si5367 is a low jitter, precision clock multiplier for
applications requiring clock multiplication without jitter
attenuation. The Si5367 accepts four clock inputs ranging
from 10 to 707 MHz and generates five frequency-multiplied
clock outputs ranging from 10 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 Si5367 input clock frequency and clock
multiplication ratio are programmable through an I
interface. The Si5367 is based on Silicon Laboratories' 3rd-
generation DSPLL
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 or 2.5 V
supply, the Si5367 is ideal for providing clock multiplication in
high performance timing applications.
