For production volume, SiTime offers factory programming of
its entire portfolio with the shortest lead time available in the
industry.
Description
SiTime offers a wide range of field programmable (FP) MEMS
oscillators including simple oscillators, differential oscillators,
high temperature oscillators, VCXO and spread spectrum
oscillators. These FP devices support the same specifications
and performance as their factory-programmed counterparts.
They enable engineers to experiment with different configura-
tions and generate customized samples in seconds for fast
prototyping.

Information
A FP device works as a superset of its programmed
counterpart. In certain cases, it can also be mapped to
different programmed base products.
As an example, SiT8008AI-71-XXX-000.FP0000 is a field
programmable device in the low power family. It comes in the
2.1 x 1.6 mm x mm package, and can be programmed to
support different combinations of the following:
• Frequency: 1 MHz to 110 MHz with 6 decimal places of
accuracy
• Frequency stability: ±20 ppm, ±25 ppm, ±50 ppm
• Temperature range: -20°C to 70°C, -40°C to 85°C
• Supply voltages: 1.8V or 2.5V to 3.3V
• Output drive strength: 8 different options for different rise/fall
time
In addition, the SiT8008AI-11--XXX-000.FP0000 can be used
for either SiT1602 or SiT8008 in the 2.0 x 1.6 mm x mm
package. The SiT1602 and the SiT8008 share similar
electrical specs and the same field programmable devices, but
they support different frequencies.
Below is a complete summary of all currently available field
programmable devices, the mapping to the programmed
devices and the supported programmable options.
