• Includes multiple on-chip regulators to filter power supply noise, removing the requirement for external Low-Dropout (LDO) linear regulators.
• Factory programmable for specific combinations of frequency, stability, voltage, output signaling, and pull range to optimize clock configurations.

Oscillators Applications

• Telecommunications systems requiring precise timing signals
• Networking equipment demanding low-jitter differential clocks
• Industrial applications subject to harsh environmental conditions

Oscillators Procurement Notes

Verify the complete part number against official SiTime documentation to ensure correct configuration parameters, including output format, voltage, and stability. Confirm that the LVDS output type and 200 MHz frequency match system requirements. Check for RoHS compliance status and ensure the 6-SMD package dimensions are compatible with the target PCB footprint. Validate that the operating temperature range meets the specific environmental constraints of the end application.

Oscillators Selection Notes

Select this component when a differential VCXO with high dynamic performance and robustness against mechanical stress is required. The integrated noise filtering simplifies board design by eliminating external LDOs. Ensure the system can accommodate the 84 mA maximum current draw and the specific 2.8 V operating voltage. Consider the ±50 ppm stability and ±745 ppm pull range for frequency tuning requirements in telecom or industrial environments.
