QVMQF326T33-2.0A-74.250

Oscillators Overview

The QVMQF326T33-2.0A-74.250 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 74.25 MHz and utilizes CMOS output logic levels. The device is designed for high stability, offering a frequency tolerance of ±2.0 ppm across the operating temperature range of -40°C to +85°C. It functions on a single 3.3V supply voltage and features an enable/disable control pin for power management. The component is housed in a compact 6-SMD, No Lead package with dimensions of 3.2mm x 2.5mm x 1.6mm.

Oscillators Feature Summary

• Integrated temperature compensation ensures stable frequency performance across wide industrial temperature ranges.

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 3.3V supply voltage aligns with your power architecture. Ensure the 6-SMD package footprint matches your PCB layout guidelines. Request the official datasheet from Mercury Electronics for detailed electrical characteristics and reliability data prior to final procurement decisions.

Oscillators Selection Notes

Select this model when precise frequency stability within ±2.0 ppm is required over varying thermal conditions. The CMOS output simplifies integration into digital systems compared to LVDS or ECL variants. Consider the enable/disable feature if power conservation during idle states is a priority. Evaluate the physical dimensions against available board space constraints.

Oscillators Part Context

This component belongs to the QuikXO VCTCXO series from Mercury Electronics, which focuses on providing cost-effective yet reliable oscillators for consumer and industrial electronics. The QVMQF326T33 designation indicates the specific series, voltage, and package type, while the suffix denotes the exact frequency. This series is positioned between standard TCXOs and higher-performance OCXOs in terms of performance and cost.

Oscillators Replacement Considerations

Direct replacements must match the 74.25 MHz frequency, ±2.0 ppm tolerance, 3.3V operation, and 6-SMD package. Verify pinout compatibility and enable signal polarity. Cross-reference with other Mercury VCTCXO models or competitors offering identical electrical specifications and form factors to ensure seamless substitution without redesigning the host circuitry.
