18QHTF21-45.600-PD

Oscillators Overview

The 18QHTF21-45.600-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 45.6 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic levels
• Includes standby or power down functionality for energy management
• Utilizes a surface-mount 4-pin no-lead package design

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application's specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout design to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS compatibility. The inclusion of a standby mode makes it suitable for battery-powered or power-sensitive applications. Consider the small 2.00mm x 1.60mm footprint for space-constrained designs requiring reliable quartz-based timing solutions from established manufacturers.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides precise timing solutions using quartz technology. Mercury Electronic has over 50 years of experience in manufacturing frequency control products, including crystals, oscillators, and filters. This specific model represents their standard oscillator line designed for modern low-voltage digital electronics.

Oscillators Replacement Considerations

Direct substitutes include other 45.6 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as phase noise and jitter when considering alternative brands.
