SIT9120AC-1D3-XXS50.000000

Oscillators Overview

The SiTime SIT9120AC-1D3-XXS50.000000 is a MEMS-based standard clock oscillator operating at 50 MHz with ±50 ppm frequency stability. It utilizes a 7050 (7.0mm x 5.0mm) surface-mount package and functions within an industrial temperature range of -20°C to +70°C. The device supports a supply voltage of 3.3V, with operational limits between 2.97V and 3.63V. It features LVPECL output format and includes an active-low enable pin for power management control.

Oscillators Feature Summary

• MEMS technology provides robustness against shock and vibration compared to traditional quartz solutions.
• LVPECL output format ensures high-speed signal integrity for demanding digital interfaces.
• Integrated enable pin allows for precise power management and system synchronization.

Oscillators Applications

• High-speed data communication equipment requiring stable clock sources
• Industrial automation systems operating in extended temperature environments
• Network infrastructure components utilizing LVPECL signaling standards

Oscillators Procurement Notes

Verify the specific suffix configuration against the official SiTime datasheet to ensure compatibility with required frequency tolerance and output drive levels. Confirm that the 7050 package dimensions align with PCB footprint constraints. Check for RoHS compliance status and lead-free soldering requirements relevant to your manufacturing process before finalizing procurement orders.

Oscillators Selection Notes

Select this model when a 50 MHz reference with moderate ±50 ppm stability is sufficient for the application. The 7050 package offers larger board space utilization but may provide improved thermal performance over smaller footprints. Ensure the design accommodates LVPECL termination resistors and the 3.3V supply rail requirements specified in the electrical characteristics.

Oscillators Part Context

This component belongs to the SiT9120 series of MEMS oscillators from SiTime. The series is designed to replace traditional quartz crystals and resonators in various electronic applications. The AC variant typically denotes specific commercial or industrial grade specifications within the broader product family lineup.

Oscillators Replacement Considerations

Direct replacements must match the 50 MHz frequency, LVPECL output, and 7050 package size. Verify that substitute parts support the same 3.3V supply and -20°C to +70°C operating range. Cross-reference pinout configurations to ensure compatibility without circuit redesign.
