The device requires a supply voltage of 1.8V and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• LVCMOS output interface
• Enable/Disable control capability
• Compact 4-SMD surface mount package

Applications

• General purpose timing circuits
• Embedded systems clock sources
• Consumer electronics timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD package footprint matches your PCB layout constraints to avoid assembly issues.

Selection Notes

Select this component when a low-voltage, small-footprint oscillator is required for digital logic interfaces. The LVCMOS output is suitable for direct connection to microcontrollers or FPGAs operating at 1.8V. Consider the enable pin if power saving during idle states is necessary for the application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, designed for applications requiring precise timing in space-constrained environments. The series offers various frequencies and voltages, with this specific model providing 10.41 MHz at 1.8V. It is commonly used in portable devices where size and power efficiency are critical.

Replacement Considerations

Direct substitutes may include other 10.41 MHz LVCMOS oscillators in 2.0x1.6mm packages from manufacturers like Epson, NDK, or SiTime. Verify pinout compatibility and electrical specifications such as jitter and phase noise before substitution.
