Description

The Si5317-EVB User’s Guide provides a complete and
simple evaluation of the functions, features, and
performance of the Si5317. 
The Si5317 is a pin-controlled 1:1 jitter-attenuating
clock for high-performance applications.
The Si5317 is based on Skyworks Solutions' 3rd-
generation DSPLL® technology, which provides any-
rate jitter attenuation in a highly integrated PLL solution
that eliminates the need for external VCXO and loop
filter components. The DSPLL loop bandwidth is user
programmable, providing jitter performance optimization
at the application level.

Features



No software required. Simple jumpers for device



Fully powered from either a single USB port or an 

external power supply



Selectable external reference clock or on-board 

crystal



Status LEDs



Header to connect to external test equipment for 

automated testing
