Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure compatibility with your design requirements. Confirm that the LVPECL output level and 2.5V supply voltage match your system's power rails. Check the operating temperature range limits for your intended environment. Ensure the 6-pin surface mount footprint aligns with your PCB layout guidelines before finalizing procurement.

Oscillators Selection Notes

Select this component when designing systems that require high reliability under mechanical stress, such as industrial or automotive environments. The MEMS architecture provides better immunity to shock and vibration than quartz alternatives. Consider the LVPECL interface if your downstream PHY or transceiver requires this specific logic family. Verify that the ±25 ppm stability meets your network synchronization specifications.

Oscillators Part Context

This part belongs to the SiT9365 series of ultra-low jitter differential oscillators from SiTime.
