18QHTF21-1.180-OE

Overview

The 18QHTF21-1.180-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 1.18 MHz and utilizes LVCMOS output logic levels. The device requires a 1.8V supply voltage and includes an Enable/Disable control function 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 logic compatibility
• Integrated Enable/Disable functionality
• Compact 4-SMD surface mount package

Applications

• General digital timing circuits
• Embedded system clock sources
• Consumer electronics timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the OE suffix to confirm availability and lead times with authorized distributors.

Selection Notes

Select this component when a low-voltage 1.18 MHz reference is required. The LVCMOS interface ensures compatibility with standard digital logic families. The enable/disable feature supports power-sensitive applications. Consider the small form factor for space-constrained designs. Verify temperature stability requirements against the standard XO specifications.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The 'OE' suffix typically denotes specific packaging or testing options. This model provides a precise timing solution for applications requiring stable low-frequency clocks.

Replacement Considerations

Direct substitutes include other 1.18 MHz LVCMOS oscillators in 2.0x1.6mm packages. Check pinout compatibility and electrical parameters such as current consumption and startup time. Ensure the replacement supports the same enable/disable logic level. Verify operating temperature range alignment.
