OJ-JMGCM

Overview

The Taitien OJ-JMGCM is a programmable crystal oscillator (XO) manufactured by Taitien Electronics Ltd. It features CML output logic and operates at a supply voltage of 2.5V. The device supports an output frequency range from 15 MHz to 2100 MHz. It is housed in a compact 4-SMD, No Lead package with dimensions of 3.2 x 2.5 mm. This component is designed for high-frequency timing applications requiring precise clock signals.

Feature Summary

• Programmable frequency generation capability within the specified range
• CML output interface for signal transmission
• Compact surface-mount package design

Applications

• High-speed digital communication systems
• Network infrastructure equipment
• Test and measurement instruments

Procurement Notes

Verify the specific frequency configuration required for your application against the manufacturer's programming options. Confirm that the 2.5V supply voltage aligns with your system power architecture. Ensure the CML output compatibility matches your receiving circuitry. Check the 3.2 x 2.5 mm footprint against your PCB layout constraints before ordering.

Selection Notes

Select this model when a programmable XO with CML outputs is needed between 15 MHz and 2100 MHz. Consider the 2.5V supply requirement and the small SMD form factor. Evaluate if the CML interface suits your downstream logic levels compared to LVDS or LVPECL alternatives available in the same series.

Part Context

The OJ-JMGCM belongs to Taitien's FASTXO OJ-M type series of programmable oscillators. This family offers various output types including LVPECL, LVDS, and HCSL alongside CML. The series supports multiple supply voltages such as 3.3V, 2.5V, and 1.8V, providing flexibility for different system designs.

Replacement Considerations

The OJ-JMGCV serves as a variant within the same series offering LVDS output instead of CML. The OJ-KMGCM is another related programmable oscillator model. Verify pinout and electrical specifications carefully when substituting these parts.
