QMQF574T33-2.0A-66.6667

Oscillators Overview

The QMQF574T33-2.0A-66.6667 is a temperature-compensated crystal oscillator (TCXO) manufactured by Mercury United Electronics, Inc. It operates at a nominal frequency of 66.6667 MHz with CMOS output logic levels. The device functions on a 3.3 V supply voltage and features an enable/disable control function. It is housed in a surface-mount 4-SMD, No Lead package with dimensions of 7.0 x 5.0 x 2.5 mm. The unit maintains a frequency stability of ±2.0 ppm over the operating temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Temperature compensation ensures stable frequency performance across wide industrial temperature ranges.
• CMOS output interface provides direct compatibility with digital logic circuits.
• Integrated enable/disable functionality allows for power management control.

Oscillators Applications

• Telecommunications base station synchronization
• High-speed data transmission equipment
• Network infrastructure timing sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Ensure the 3.3V supply voltage aligns with your system's power rails. Check for RoHS compliance status if required by your manufacturing standards. Request official datasheets from authorized distributors to confirm current production status.

Oscillators Selection Notes

Select this component when precise frequency stability is critical within a compact surface-mount form factor. The CMOS output simplifies integration into digital systems without additional level-shifting components. Consider the ±2.0 ppm stability specification for applications requiring tight timing accuracy. Evaluate the thermal environment to ensure operation within the specified -40°C to +85°C range. Compare power consumption requirements against other oscillator types available in similar packages.
