QVMQF574T33-2.0A-14.5888

Oscillators Overview

The QVMQF574T33-2.0A-14.5888 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) from the QuikXO series, manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 14.5888 MHz with a stability of ±2.0 ppm across an operating temperature range of -40°C to +85°C. The device utilizes a CMOS output signal and requires a 3.3V supply voltage. It is housed in a compact 4-pad Surface Mount Device (SMD) package measuring 7.0 x 5.0 x 2.5 mm, designed for FR4 substrates.

Oscillators Feature Summary

• Integrated temperature compensation ensures stable frequency performance across wide industrial temperature ranges.
• Compact surface-mount footprint facilitates automated assembly and space-constrained PCB layouts.
• CMOS output interface provides direct compatibility with digital logic circuits without additional buffering.

Oscillators Applications

• High-speed FPGA timing references
• Wireless communication base stations
• Precision data acquisition systems

Oscillators Procurement Notes

Verify the specific frequency tolerance and temperature range requirements against the official datasheet before procurement. Ensure that the 3.3V supply voltage aligns with the system design specifications. Confirm the 4-pad SMD package dimensions match the target PCB footprint to prevent assembly issues. Cross-reference the manufacturer's part number to avoid counterfeit components.

Oscillators Selection Notes

Select this component when precise frequency stability within ±2.0 ppm is required over a -40°C to +85C environment. The CMOS output level makes it suitable for direct interfacing with standard digital logic families. Consider the 7.0x5.0x2.5mm package size for applications where board real estate is limited but higher stability than standard TCXOs is necessary.

Oscillators Part Context

This model belongs to the QuikXO VCTCXO series, which emphasizes high stability and rapid availability. The QVMQF574T33 designation indicates a specific pinout and electrical configuration within the Mercury Electronics portfolio. These oscillators are engineered for demanding applications requiring reliable clock signals in harsh thermal conditions.

Oscillators Replacement Considerations

Direct substitutes must match the 14.5888 MHz frequency, ±2.0 ppm stability, 3.3V CMOS output, and 4-pad SMD package dimensions. Verify thermal compensation characteristics and control voltage ranges if applicable. Consult the manufacturer's cross-reference list for validated equivalent parts.
