OJ-JMELH

Overview

The Taitien OJ-JMELH is a programmable crystal oscillator (XO) housed in a 4-SMD, no lead package with dimensions of 5.00mm x 3.20mm and a maximum seated height of 1.55mm. It operates at a typical supply voltage of 2.5V and supports output frequencies ranging from 15MHz to 2.1GHz. The device provides HCSL clock output and complies with ROHS3 standards.

Feature Summary

• Programmable frequency generation capabilities
• Support for HCSL output interface
• Low power operation at 2.5V supply

Applications

• High-speed data communication systems
• Network infrastructure equipment
• Server and storage applications

Procurement Notes

Verify the specific output frequency configuration required for your design, as this is a programmable device. Confirm that the HCSL output level matches your receiver input requirements. Ensure the 5.00mm x 3.20mm footprint aligns with your PCB layout constraints. Check for any specific programming tools or software needed to set the desired frequency before ordering.

Selection Notes

Select this component when a precise, programmable clock signal is needed within the 15MHz to 2.1GHz range. The HCSL output is suitable for high-speed serial links requiring low swing signals. Consider the 2.5V supply voltage compatibility with your system's power rails. The compact SMD package aids in space-constrained designs.

Part Context

This part belongs to Taitien's FASTXO series, which offers various supply voltage options including 3.3V, 2.5V, and 1.8V. The series supports multiple output types such as LVPECL, LVDS, CML, and HCSL. These oscillators are designed for applications demanding low phase noise and wide temperature stability.

Replacement Considerations

Direct substitutes may include other Taitien programmable XOs in similar packages like the OJ-JMELH-DG variant. Cross-reference pinouts and electrical characteristics carefully. Verify that alternative parts support the same HCSL output format and frequency range.
