Overview
The 18QHTF21-1.415-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 1.415 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component is designed for surface-mount applications and features a maximum supply current of 21mA.
Feature Summary
- Integrates LVCMOS output logic for standard digital interface compatibility
- Includes enable/disable pin functionality to manage power consumption states
- Utilizes a quartz crystal base resonator for stable frequency generation
- Designed in a small form factor 4-SMD no-lead package for space-constrained layouts
Applications
- General-purpose clock signal generation in embedded systems
- Timing reference sources for microcontrollers and processors
- Synchronization circuits in consumer electronic devices
- Industrial control equipment requiring precise frequency standards
Procurement Notes
Verify the specific frequency tolerance and operating temperature range against your system requirements before ordering. Confirm that the 1.8V supply voltage aligns with your board's power rails. Ensure the LVCMOS output swing is compatible with the receiving logic inputs. Check for any specific handling or storage conditions required for the SMD package. Validate the lead time and availability status directly with authorized distributors.
Selection Notes
Select this component when a low-power, small-footprint oscillator is required for 1.415 MHz applications. Consider the enable/disable feature if power efficiency is critical. Compare performance metrics such as phase noise and stability against alternative models in the 18QHTF21 series. Ensure the package size fits within the available PCB area constraints.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series offers various frequencies and packages, catering to diverse timing needs. Mercury Electronics is a specialized manufacturer of frequency control products, including crystals and oscillators, with a long history in the industry.
Replacement Considerations
Direct substitutes include other variants within the 18QHTF21 series with matching frequency and package, such as 18QHTF21-1.000-OE or 18QHTF21-14.1875-OE, provided the frequency difference is acceptable. Cross-referencing with similar LVCMOS XO components from other manufacturers requires verification of electrical parameters and pinout compatibility.
