18QHTF21-13.800-OE

Overview

The 18QHTF21-13.800-OE is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.8 MHz with LVCMOS output logic and a supply voltage of 1.8V. The device features an Enable/Disable control pin and offers a frequency stability of ±50ppm. It is designed for surface mount applications within the -40°C to +85°C temperature range, consuming a maximum supply current of 22mA.

Feature Summary

• Ultra-stable performance suitable for low-jitter designs
• Integrated enable/disable functionality for power management
• Compact surface-mount package design

Applications

• Low-jitter circuit designs
• Consumer electronics requiring precise timing
• Industrial equipment operating in wide temperature ranges

Procurement Notes

Verify the specific suffix 'OE' corresponds to the required enable/disable feature and LVCMOS output type. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the ±50ppm stability meets your application's timing requirements. Check the operating temperature range against environmental conditions.

Selection Notes

Select this component when a 1.8V LVCMOS oscillator with enable control is required. Consider the ±50ppm stability and -40°C to +85°C range for suitability. Evaluate the 22mA max current consumption against power budgets. Compare against other Mercury models if different frequencies or voltages are needed.
