OJ-KMELM

Overview

The Taitien OJ-KMELM is a programmable crystal oscillator (XO) featuring CML differential output. It operates within a frequency range of 15 MHz to 2100 MHz and supports a 1.8V supply voltage with enable/disable functionality. The component utilizes a 4-SMD, no-lead package design. This series belongs to the FASTXO OJ-M type family, which also offers 3.3V and 2.5V supply options and alternative outputs such as LVPECL, LVDS, and HCSL.

Feature Summary

• Programmable frequency generation capability across a wide spectrum
• CML differential output interface for high-speed signal integrity
• Integrated enable and disable control function
• Compact surface-mount package construction

Applications

• Data center infrastructure
• Edge computing servers
• Fiber optic communication systems
• Wired communication networks

Procurement Notes

Verify the specific suffix against the official datasheet to confirm output format and voltage. Ensure the procurement channel provides authentic Taitien documentation. Confirm package compatibility with PCB footprint requirements before ordering.

Selection Notes

Select this model when CML output is required for frequencies up to 2100 MHz. Consider other variants in the OJ-M series if LVDS or LVPECL outputs are needed instead. Verify that the 1.8V supply constraint aligns with system power architecture.

Part Context

This component is part of Taitien's FASTXO OJ-M series, designed for high-performance timing applications. The manufacturer specializes in quartz frequency control components, including OCXOs and TCXOs. The OJ-M series targets demanding environments requiring precise clock signals for modern digital infrastructure.

Replacement Considerations

Check for OJ-KMDCV (LVDS output) or OJ-KMELH (HCSL output) if different signaling standards are required. Other models in the OJ-M family may offer 3.3V or 2.5V supplies if voltage levels differ.
