SIT8009AC-31-18E-125.000000 Description

Short technical summary and product information.

The SiTime SIT8009AC-31-18E-125.000000 is a high-frequency, low-power MEMS oscillator from the SiT8009 family. It provides a precise 125MHz LVCMOS output clock with a frequency stability of ±20ppm, inclusive of initial tolerance, aging, and variations over temperature, supply voltage, and load.

 

This oscillator operates from a 1.8V supply voltage (1.62V to 1.98V range) and consumes only 4.8mA typical (5.6mA maximum) at 125MHz with no load. It features an enable/disable function on pin 1, allowing the output to be tri-stated for power savings. The device supports an extended commercial temperature range of -20°C to +70°C.

 

The SIT8009AC-31-18E-125.000000 is housed in a compact 4-SMD, no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.80mm, making it suitable for space-constrained surface-mount designs. It is Pb-free, RoHS, and REACH compliant.
