18QHTF21-13.52127-OE

Overview

The 18QHTF21-13.52127-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 13.52127 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with a maximum seated height. The unit supports a frequency stability of ±50ppm and draws a maximum supply current of 22mA.

Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Includes hardware enable and disable control functionality
• Designed for low-voltage operation at 1.8V
• Utilizes a leadless surface-mount package for space-constrained layouts

Applications

• Timing and clock signal generation in electronic devices
• Consumer electronics requiring precise frequency references
• Industrial control systems needing stable clock sources

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system power rails. Ensure the 4-SMD no-lead footprint matches the PCB land pattern design to prevent assembly issues.

Selection Notes

Select this component when a 13.52127 MHz reference is required with LVCMOS outputs. Consider the ±50ppm stability requirement for timing accuracy. Evaluate the 22mA max current consumption against system power budgets. Verify the 1.8V supply constraint fits the available voltage domain.
