18QHTF21-75.600-PD

Overview

The 18QHTF21-75.600-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 75.6 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is designed for timing applications requiring precise frequency control in portable electronics.

Feature Summary

• Supports low-voltage operation at 1.8V for efficient power consumption
• Includes standby mode to reduce current draw during inactive periods
• Provides stable LVCMOS output signals for digital circuit interfacing

Applications

• Portable electronic devices requiring low power consumption
• Battery-powered systems needing extended operational life
• Digital communication equipment utilizing standard clock signals

Procurement Notes

Verify the specific ordering suffix and package type against official Mercury Electronics documentation to ensure compatibility. Confirm that the 1.8V supply requirement aligns with your system design. Check for any RoHS compliance statements in the latest datasheet. Ensure the 4-SMD no-lead package matches your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 75.6 MHz clock signal is required with minimal power usage. The 1.8V operating voltage makes it suitable for modern low-voltage digital circuits. Consider the standby feature if power management is critical. The small 2.0x1.6mm package allows for dense board layouts. Verify temperature range specifications against your environmental conditions.

Part Context

This part belongs to the Mercury Electronic 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and voltage options within a standardized 4-SMD package.
