Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required output format, voltage, and stability specifications. Confirm the package dimensions align with the PCB footprint design. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the manufacturer part number with official datasheets to confirm availability and lead times before finalizing procurement plans.

Oscillators Selection Notes

Select this component when a differential VCXO with LVPECL outputs is required for 80 MHz applications. Consider the integrated noise filtering capabilities if space constraints prevent the use of external LDOs. Evaluate the MEMS robustness against mechanical stress compared to quartz alternatives. Verify that the ±25 ppm stability specification satisfies the system's jitter and phase noise requirements.

Oscillators Part Context

This model belongs to the SiT3372 Elite Platform series, which offers ultra-low jitter differential oscillators ranging from 1 MHz to 220 MHz. The AC suffix typically denotes commercial temperature grades, while the 1B2 coding indicates specific electrical characteristics such as voltage and output type. This platform replaces traditional quartz devices by offering immediate availability and customizable parameters.

Oscillators Replacement Considerations
