Si537X-EVB EVALUATION BOARD USERS GUIDE
Description
The Si5374/75/76 Any Frequency Precision Clocks are
based on Silicon Labs 3rd-generation DSPLL
technology, which provides any-frequency synthesis in
a highly integrated PLL solution that eliminates the need
for external VCXO and loop filter components. The
devices have excellent phase noise and jitter
performance. All of the devices support 350 fs RMS
jitter generation across the 12 kHz to 20 MHz jitter filter
bandwidth. For all devices, the DSPLL loop bandwidth
is digitally programmable, providing jitter performance
optimization at the application level. These devices are
ideal for providing clock multiplication/clock division and
jitter attenuation in mid-range and high-performance
timing applications where printed circuit board real
estate is at a premium.
Features
The Si537x-EVB includes the following:
CD with documentation and EVB software including
the Si537x_DSPLLsim configuration software utility.
