18QHTF21-10.245-OE

Overview

The 18QHTF21-10.245-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 10.245 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component is designed for surface mount applications.

Feature Summary

• Integrates an enable/disable function to manage power consumption effectively
• Utilizes LVCMOS output logic for digital circuit compatibility
• Features a compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Embedded systems requiring low power operation
• Digital communication interfaces

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the LVCMOS output levels are compatible with the receiving logic inputs. Check for any specific handling requirements related to the surface mount package type during assembly.

Selection Notes

Select this component when a precise 10.245 MHz reference is required alongside power-saving capabilities. The integrated enable pin makes it suitable for battery-operated devices where standby current reduction is critical. Consider the small 2.0x1.6 mm footprint for space-constrained PCB layouts. Ensure the operating temperature range meets the environmental conditions of the final application.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronic, which specializes in quartz timing solutions. The series typically offers various frequencies and supply voltages within a standardized small outline package. Mercury Electronic has established itself as a supplier of frequency control products, including crystals and oscillators, serving global electronics markets.

Replacement Considerations

Direct substitutes must match the 10.245 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent electrical parameters such as phase noise and stability if available in public documentation.
