FO7HHAAE25.0-T1

Oscillators Overview

The FO7HHAAE25.0-T1 is a standard crystal oscillator (XO) manufactured by Fox Electronics, operating at a nominal frequency of 25.0 MHz. It utilizes HCMOS output logic and requires a 5V power supply with a maximum current consumption of 40mA. The device features an enable/disable function for power management control. It is housed in a compact 4-SMD, no-lead package measuring 7.50mm x 5.20mm x 1.50mm. The unit supports a commercial temperature range of -10°C to +70°C and maintains a frequency stability of ±100ppm.

Oscillators Feature Summary

• Integrated enable/disable pin allows for active power state control and standby mode operation.
• Standard HCMOS output provides direct compatibility with digital logic interfaces without additional level shifting.
• Compact surface-mount footprint facilitates automated assembly and space-constrained PCB layouts.

Oscillators Applications

• Industrial data acquisition gateways requiring stable system clocks
• Embedded controller systems needing precise timing references
• Communication equipment utilizing standard serial or parallel buses

Oscillators Procurement Notes

Verify the specific suffix configuration against design requirements, as model variations exist for different stability grades and temperature ranges. Confirm that the commercial temperature rating (-10°C to +70°C) aligns with the operational environment, as industrial variants offer wider thermal coverage. Ensure the 5V supply voltage matches the target circuit's power rail specifications before finalizing procurement.

Oscillators Selection Notes

Select this component when a 25MHz clock source with ±100ppm stability is sufficient for the application. Consider alternative series members if the environment exceeds the commercial temperature limit or if tighter frequency tolerance is required. Evaluate the 40mA current draw against available power budget constraints. Verify that the HCMOS output swing meets the input threshold requirements of the downstream load.

Oscillators Part Context

This part belongs to the FO7HH series of surface-mount oscillators from Fox Electronics. The series offers various frequency options and stability grades within a standardized 7x5mm package. It serves as a replacement for legacy through-hole crystals in modern high-density designs, providing reliable timing solutions for general-purpose electronic applications.

Oscillators Replacement Considerations

Direct substitutes include other Fox Electronics models within the same FO7HH family sharing identical electrical parameters and pinout configurations. Cross-manufacturer replacements require verification of pin compatibility, output logic levels, and physical dimensions to ensure board-level interchangeability.
