VTEUMLJANF-2.048000

Oscillators Overview

The VTEUMLJANF-2.048000 is a Voltage-Controlled Crystal Oscillator (VCXO) manufactured by Taitien, designed for surface-mount applications. It operates at a nominal frequency of 2.048 MHz with CMOS output characteristics. The device supports a supply voltage range from 2.97 V to 3.63 V, typically utilizing 3.3 V. Key electrical specifications include a maximum control voltage of 3 V and a minimum of 0.3 V. The oscillator features a pullability of 50 ppm and a frequency stability of 25%. Physical dimensions are 3.2 mm x 2.5 mm x 1.2 mm, with rise and fall times capped at 4 ns.

Oscillators Feature Summary

• Voltage-controlled operation enabling precise frequency adjustment via external control voltage.
• CMOS output interface compatible with standard digital logic circuits.
• Integrated enable/disable functionality allowing for low-power standby modes.

Oscillators Applications

• Clock generation in telecommunications equipment requiring frequency agility.
• Data communication systems needing stable reference signals with tuning capabilities.
• Consumer electronics utilizing VCXOs for timing synchronization.

Oscillators Procurement Notes

Verify the specific suffix codes against official Taitien documentation to confirm pinout, tolerance, and packaging details. Ensure compatibility with existing PCB footprints and thermal requirements. Confirm availability status as manufacturing schedules may change. Cross-reference environmental compliance certifications such as RoHS if required for your region.

Oscillators Selection Notes

Select this component when a fixed-frequency crystal is insufficient due to the need for frequency trimming or compensation. Evaluate the required pull range against the 50 ppm specification. Consider the operating temperature range and load capacitance requirements to ensure system-level stability. Compare power consumption metrics against alternative oscillators if battery life is a critical constraint.

Oscillators Part Context

This part belongs to Taitien's VT series of surface-mount crystal oscillators. The series includes various configurations such as XO, TCXO, and VCXO types. The VTEUMLJANF variant specifically addresses applications requiring voltage-tunable frequency outputs within a compact SMD package, distinguishing it from non-tunable counterparts in the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 2.048 MHz frequency, VCXO functionality, and 3.2x2.5mm footprint. Verify that alternative manufacturers offer comparable pullability and CMOS output levels. Check for pin-to-pin compatibility regarding control voltage inputs and enable functions before integration.
