18QHTF21-75.405-PD

Overview

The 18QHTF21-75.405-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 75.405 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a standby function for power down control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. The unit supports an operating temperature range of -40°C to 85°C and maintains a frequency stability of ±50ppm.

Feature Summary

Supports low voltage operation at 1.8V
Includes standby capability for power management
Utilizes LVCMOS output interface

Applications

General purpose clock signal generation
Embedded system timing references
Consumer electronics circuit boards

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail is stable within the specified operating temperature range. Ensure the PCB footprint matches the 4-SMD no lead package dimensions exactly to prevent soldering defects during assembly.

Selection Notes

Select this component when a precise 75.405 MHz reference is required for low-power applications. The ±50ppm stability suits most digital communication interfaces. Consider the small 2.0x1.6mm form factor for space-constrained layouts. Verify compatibility with the host controller's input voltage thresholds.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, designed for high-density surface mount applications. The series offers various frequencies with consistent electrical characteristics. It serves as a reliable timing source for modern electronic devices requiring compact footprints and low current consumption.

Replacement Considerations

Direct substitutes must match the 75.405 MHz frequency, 1.8V supply, and LVCMOS output. Compatible packages include 4-SMD no lead variants with identical 2.0x1.6mm dimensions. Verify thermal performance and stability ratings align with the original specification.
