Overview
The 18QHTF21-14.060-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 14.06 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.
Feature Summary
- Supports LVCMOS output logic for digital interface compatibility
- Integrates enable/disable functionality for power efficiency
- Utilizes a leadless surface-mount package design
Applications
- General clock signal generation in embedded systems
- Timing reference sources for low-voltage digital circuits
- Consumer electronics requiring compact oscillators
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors during manufacturing.
Selection Notes
Select this component when a precise 14.06 MHz timing source is required within space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power applications. Consider the enable pin if dynamic power saving is necessary. Compare performance against other Mercury 18QHTF series variants for similar form factors.
Part Context
This part belongs to the 18QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized small outline package. It serves as a direct replacement for legacy through-hole crystals where stability and ease of integration are prioritized over manual tuning.
Replacement Considerations
Direct substitutes include other 14.06 MHz LVCMOS oscillators in 2.0x1.6mm packages from compatible manufacturers. Verify pinout compatibility and electrical specifications such as current consumption and startup time before swapping components.
