18QHTF21-75.565-PD

Overview

The 18QHTF21-75.565-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a nominal frequency of 75.565 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features a Standby (Power Down) control function for power management. It is housed in a compact 2.0 x 1.6 mm surface-mount package, suitable for space-constrained applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes Standby (Power Down) functionality to reduce power consumption
• Compact 2.0 x 1.6 mm surface-mount package design

Applications

• Digital signal processing systems
• Communication equipment timing circuits
• Embedded system clock generation

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 2.0 x 1.6 mm footprint matches your PCB layout constraints. Check for any specific handling instructions regarding ESD sensitivity during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The integrated standby feature makes it suitable for battery-powered or energy-efficient designs. Consider the small 2.0 x 1.6 mm package size if board real estate is limited. Ensure the 75.565 MHz frequency meets the specific timing needs of the target application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, which specializes in quartz-based timing solutions. The manufacturer has decades of experience in Taiwan's crystal industry.
