18QHTF21-75.375-PD

Overview

The 18QHTF21-75.375-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 75.375 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning with a supply voltage of 1.8V. It features a power-down mode accessible via standby control to reduce energy consumption when the oscillator is not in active use. The component is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm by 1.6mm, suitable for surface-mount assembly processes.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby power-down functionality for energy efficiency
• Utilizes a small footprint 4-SMD no-lead package design

Applications

• Timing and clock generation in electronic devices
• Digital circuit synchronization systems
• Consumer electronics requiring low-voltage clock sources

Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to ensure correct voltage and package specifications. Confirm that the required operating temperature range aligns with your system design constraints before procurement. Cross-reference the datasheet for specific electrical characteristics such as load capacitance and drive strength requirements to guarantee proper integration into the target circuit.

Selection Notes

Select this component when a precise 75.375 MHz clock signal is required for LVCMOS-compatible digital circuits. Ensure the design supports a 1.8V supply rail and accommodates the physical dimensions of the 2.0x1.6mm SMD package. Consider the power-down feature if system-level energy management is a priority during idle periods or standby modes.
