Procurement Notes
Verify the exact part number suffix to ensure correct packaging and programming status. Confirm that the application environment matches the specified temperature range and voltage requirements. Check for RoHS compliance documentation if required by regulatory standards. Ensure proper handling procedures are followed due to the surface-mount nature of the component. Validate that the supplier provides official datasheets and quality reports for traceability.
Selection Notes
Choose this component when differential LVPECL outputs are required for noise immunity. Select based on the necessary frequency range between 220 MHz and 625 MHz. Consider the ±25ppm stability requirement for system synchronization needs. Evaluate the need for programmability versus fixed-frequency alternatives. Assess power supply constraints to confirm compatibility with 2.5V or 3.3V operation.
Part Context
This part belongs to the SiT3822 series of programmable oscillators from SiTime. The series leverages MEMS technology to replace traditional quartz components. The 'AI' designation typically indicates industrial temperature range capabilities. The '1C2' suffix relates to specific package and pinout configurations. These devices are designed to offer superior reliability compared to conventional crystal oscillators.
Replacement Considerations
Direct replacements may include other SiT3822 variants with different frequency ranges or output types. Cross-reference with SiT3821 models for lower frequency requirements. Verify pin compatibility and electrical specifications before substituting. Ensure the replacement maintains the required differential output format.
