Si50x-32x4-EVB
EVALUATION BOARD FOR THE Si50X 3.2X4.0 MM
SILICON OSCILLATORS
Description
This document describes the operation of the Silicon
Laboratories Si50x-32x4-EVB Rev 2.0 evaluation board
to evaluate Silicon Laboratories' Si50x Silicon
Oscillators in the 3.2x4.0 mm package. Devices
currently available include the single-ended output
Si500S and the differential output Si500D. The Si50x
utilizes Silicon Laboratories' ultra stable silicon oscillator
technology to achieve an inexpensive low jitter clock
source. This unique oscillator technology is factory
programmed to support any frequency between
900 kHz and 200 MHz. Unlike traditional XOs that
require a unique quartz crystal resonator to generate
each frequency, the Si50x uses programmable,
compensated silicon oscillator architecture that is
capable of operating over a wide range of output
frequencies. In addition, Silicon Lab's compensated
silicon oscillator provides stability comparable to fixed
frequency crystal based oscillators. The Si50x is factory
configurable for a wide variety of user specifications
including frequency, supply voltage, output format,
output drive strength, and OE behavior. Specific
configurations are factory programmed at time of
shipment, thereby eliminating long lead times
associated with custom oscillators.
Si50x samples should be ordered at the same time as
the Si50x-32x4-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.
