Si5xx-EVB
EVALUATION BOARD FOR Si53X XOS AND Si55X VCXOS
Description
Features
This document describes the operation of the Silicon Evaluation of Silicon Laboratories' Si55x/53x family
Laboratories Si5xx-EVB evaluation board to evaluate
both Silicon Laboratories' Si55x VCXOs and Si53x XOs.
The Si55x and Si53x devices use Silicon Laboratories'
AC-coupled differential output clocks
Voltage control (V ) input port (for Si55x devices)
C
Jumper selection for multi-frequency outputs
Jumper selection for output enable
®
advanced DSPLL circuitry to provide a low-jitter clock
at high frequencies. The Si55x/Si53x IC-based device is
factory configurable for a wide variety of user
specifications including frequency, supply voltage,
output, and tuning slope. Specific configurations are
factory programmed into the Si55x/Si53x at time of
shipment, thereby eliminating the long lead times
associated with custom oscillators. Si55x/Si53x
samples should be ordered at the same time as the
Si5xx-EVB since the EVB does not come with the
device. This allows end users maximum flexibility.
Silicon Laboratories can solder down samples when
ordering an EVB; please specify when ordering.
