18QHTF21-10.720444-OE

Overview

The 18QHTF21-10.720444-OE is a standard LVCMOS clock oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.720444 MHz with a supply voltage of 1.8V. The device features an enable/disable control function and utilizes a 4-SMD, No Lead package. It offers a frequency stability of ±50ppm and functions within an operating temperature range of -40°C to 85°C. This component is part of the QuikXO series, designed for fast delivery and built-to-order production.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• RoHS compliant and REACH unaffected construction

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify that the specific order suffix matches the required frequency and voltage specifications. Confirm RoHS compliance status if environmental regulations apply. Ensure the 4-SMD No Lead package dimensions fit the target PCB layout. Check lead times as these are often built-to-order items rather than standard stock.

Selection Notes

Select this model when a precise 10.720444 MHz frequency is required for LVCMOS compatible circuits. The 1.8V supply voltage suits low-power applications. Consider the ±50ppm stability requirement against system jitter tolerance. The enable pin allows for power management strategies in battery-operated devices.

Part Context

This oscillator belongs to the QuikXO series from Mercury Electronic Ind. Co., Ltd. The series specializes in CMOS output clock oscillators available in standard or custom frequencies. Mercury Electronics has a history of manufacturing quartz crystals and frequency control products since 1973.

Replacement Considerations

Direct substitutes must match the 10.720444 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify equivalent stability and temperature range requirements before substitution.
