18QHTF21-10.200-OE

Overview

The 18QHTF21-10.200-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.2 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, no lead package, designed for surface-mount applications. This component provides accurate timing signals suitable for digital circuits requiring precise clock synchronization.

Feature Summary

• LVCMOS output interface for direct digital logic compatibility
• Integrated enable/disable pin for active power control
• Leadless SMD package design for automated assembly

Applications

• Portable consumer electronics requiring low power consumption
• Digital signal processing systems needing stable clock sources

Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and package variant matches your design requirements. Confirm that the 1.8V supply voltage aligns with your system's power rails. Check for any specific environmental ratings or tolerance specifications if operating in extreme conditions. Ensure the no-lead package footprint corresponds exactly to your PCB layout guidelines to avoid soldering issues during assembly.

Selection Notes

Select this oscillator when a low-voltage 1.8V operation is required alongside LVCMOS signaling. Consider the enable/disable feature if power efficiency is critical for battery-operated devices. The small form factor makes it suitable for space-constrained designs. Verify that the 10.2 MHz frequency meets the system's timing needs without requiring additional dividers or multipliers.
