OJ-EMGCM

Overview

The OJ-EMGCM is a programmable crystal oscillator (XO) manufactured by Taitien. It features a CML output interface and operates on a 3.3V supply voltage with enable/disable functionality. The device supports an output frequency range from 15 MHz to 2100 MHz. It utilizes a 4-SMD, no-lead package design suitable for surface mount applications.

Feature Summary

• Programmable output frequency capability spanning 15 MHz to 2100 MHz
• CML differential output signal format for high-speed data transmission
• Integrated enable and disable control function for power management

Applications

• High-speed serial communication interfaces
• Data center server clock distribution
• Edge computing infrastructure timing
• Fiber optic transceiver modules

Procurement Notes

Verify the specific target frequency configuration required for your application during procurement, as this is a programmable component. Confirm that the CML output logic level matches the receiving input specifications of your downstream circuitry. Ensure the 3.3V supply voltage aligns with your system power architecture before placing orders.

Selection Notes

Select this model when a wide frequency tuning range up to 2.1 GHz is necessary within a compact SMD footprint. The CML output is optimal for low-voltage swing applications requiring high bandwidth. Consider the enable pin utility if dynamic power saving or clock gating is part of the system design requirements.

Part Context

This component belongs to Taitien's OJ-M series of FASTXO oscillators. This family provides various output types including LVPECL, LVDS, and HCSL alongside CML. The series is engineered for demanding environments in telecommunications and computing sectors requiring precise frequency control.

Replacement Considerations

Compatible alternatives within the same product line include the OJ-EMGLH and OJ-EMGCV models. These variants offer different output formats such as LVDS or LVPECL while maintaining similar programmable frequency ranges and package dimensions.
