• Supports HCSL output interface standard
• Engineered for low-jitter performance applications

Oscillators Applications

• Low-jitter clock distribution systems
• Data communication interfaces requiring precise timing
• Telecommunications equipment

Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required supply voltage of 2.8V and the HCSL output configuration. Confirm the package type corresponds to the 6-SMD No Lead Exposed Pad specification. Ensure the frequency stability requirement aligns with the ±35 ppm tolerance. Check the operating temperature range compatibility for the intended environment.

Oscillators Selection Notes

Select this component when a 50 MHz VCXO with HCSL outputs is required. Consider the 2.8V supply constraint compared to other variants. Evaluate the ±35 ppm stability against system jitter budgets. Compare the SMD7050-6P footprint against available PCB space.

Oscillators Part Context

This part belongs to the SiT3372 family of ultra-low jitter differential MEMS VCXOs. The series supports frequencies from 1 MHz to 220 MHz and offers various output types including LVPECL, LVDS, and HCSL. The AI-4E9 suffix indicates specific pinout and electrical characteristics distinct from other family members.

Oscillators Replacement Considerations

Direct substitutes include SIT3372AI-4E9-33NG50.000000 if a 3.3V supply is acceptable. SIT3372AI-4E9-28NG100.000000 serves as a replacement for 100 MHz requirements. Verify pin compatibility and thermal specifications before substitution.
