OJ-JMELM

Overview

The OJ-JMELM is a programmable crystal oscillator manufactured by Taitien Electronics. It operates within a frequency range of 15 MHz to 2100 MHz and utilizes CML output signaling. The device supports a 2.5V supply voltage with integrated enable/disable functionality. It is housed in a compact 4-SMD, no-lead package, specifically identified as SMD5032-8P. This component is designed for high-frequency applications requiring precise clock generation.

Feature Summary

• Programmable frequency generation capability across a wide spectrum
• CML differential output interface for high-speed data transmission
• Integrated enable and disable control pin for power management

Applications

• Data center infrastructure clocking
• Edge computing server systems
• Fiber optic communication equipment
• Wired network interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct output format and voltage levels. Confirm that the requested part matches the SMD5032-8P package dimensions. Check for RoHS compliance status if required by project specifications. Ensure the enable/disable function aligns with system power sequencing requirements before final procurement.

Selection Notes

Select this component when a programmable solution is required for frequencies up to 2.1 GHz. The CML output is suitable for high-speed serial links. Consider the 2.5V supply constraint during power rail design. The small form factor aids in dense PCB layouts. Verify jitter performance requirements against application needs, as specific phase noise data must be confirmed via the detailed datasheet.

Part Context

This model belongs to the FASTXO OJ-M series from Taitien Electronics. The series offers low power supply voltage options including 3.3V, 2.5V, and 1.8V variants. The OJ-M type family supports multiple output formats such as LVPECL, LVDS, CML, and HCSL. Taitien specializes in quartz frequency control components developed since 1976.

Replacement Considerations
