18QHTF21-10.6244-OE

Overview

The 18QHTF21-10.6244-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.6244 MHz with LVCMOS output logic and a supply voltage of 1.8V. The device features an enable/disable control function and is housed in a compact 4-SMD, no lead package measuring 2.0 x 1.6 mm. It supports surface mount mounting and offers a frequency stability of ±50 ppm across an operating temperature range of -40°C to 85°C, with a maximum supply current of 21 mA.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable and disable control functionality
• Designed for surface mount assembly in compact packages

Applications

• General clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring precise frequency standards

Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature and pinout configuration. Ensure the required operating temperature range (-40°C to 85°C) aligns with your system environment. Cross-reference the 1.8V supply requirement with your power rail specifications before integration.

Selection Notes

Select this component when a 10.6244 MHz clock source is required with LVCMOS outputs. Consider the ±50 ppm stability specification for timing accuracy needs. The 2.0x1.6mm footprint suits space-constrained designs. Confirm that the 1.8V supply voltage matches your system architecture and that the enable pin can be utilized if power management is necessary.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'OE' suffix likely denotes specific operational characteristics or packaging variants within this family, distinguishing it from other suffixes like 'PD'.

Replacement Considerations

Direct substitutes must match the 10.6244 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package dimensions. Verify equivalent stability and temperature ranges. Consult manufacturer cross-reference lists for confirmed compatible parts.
