Procurement Notes
This specific part number represents an unprogrammed blank device intended for user programming. Verify that the design includes necessary configuration tools or firmware to define the final frequency and control parameters before integration. Confirm compatibility with the target system's voltage levels and signal integrity requirements during the procurement phase.
Selection Notes
Select this component when a programmable VCXO with LVDS outputs is required for frequencies between 220 MHz and 625 MHz. Ensure the application can accommodate the 6-SMD package size and supports the 2.5 V or 3.3 V operating voltages. Consider the need for post-purchase programming capabilities inherent to the blank device format.
Part Context
The SIT3822 series belongs to SiTime's portfolio of high-performance differential VCXOs. These devices leverage MEMS technology to replace traditional quartz oscillators, offering greater flexibility through programmability. The AI suffix indicates industrial temperature range performance, while the 2C2 code specifies the LVDS output type and package variant.
