Oscillators Procurement Notes

Verify the complete part number against official SiTime documentation to ensure correct configuration. Confirm that the ordering suffix matches the required output format, voltage, and stability specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Oscillators Selection Notes

Select this component when low-jitter differential clocking is required in space-constrained designs. The integrated power regulation simplifies PCB layout by removing external filtering components. Ensure the application environment falls within the specified temperature range and that the HCSL output interface is compatible with the receiving logic inputs.

Oscillators Part Context

This model belongs to the SiT3372 Elite Platform series, which offers ultra-low jitter performance. The platform provides extensive programmability to replace custom quartz solutions, reducing lead times and customization costs. It is designed for high-reliability applications where environmental robustness and signal integrity are critical priorities.

Oscillators Replacement Considerations

Direct replacements require matching the 15.36 MHz frequency, HCSL output type, and 3.3V supply voltage. Verify that substitute devices support the same ±25 ppm stability and 6-pin SMD package dimensions to maintain board compatibility without mechanical redesign.
