Si5xx5x7-EVB
EVALUATION BOARD FOR Si53X/55X/59X XOS/VCXOS
Description
Features
This document describes the operation of the Silicon
Laboratories Si5xx5x7-EVB evaluation board to
evaluate both Silicon Laboratories' Si55x and Si595
VCXOs and Si53x and Si590/591 XOs. The Si53x/55x/
59x devices use Silicon Laboratories' advanced
DSPLL^® circuitry to provide a low-jitter clock at high
frequencies. The Si55x/Si53x/59x 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/59x at time of
shipment, thereby eliminating the long lead times
associated with custom oscillators. Si55x/Si53x/59x
samples should be ordered at the same time as the
Si5xx5x7-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.
