18QHTF21-45.160-OE

Oscillators Overview

The 18QHTF21-45.160-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 45.16 MHz and utilizes LVCMOS output logic for digital signal interfacing. The device functions with a supply voltage of 1.8V and includes an enable/disable control pin for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Features a dedicated enable/disable pin for active power state control
• Utilizes a leadless SMD package optimized for automated surface-mount placement

Oscillators Applications

• Digital clock signal generation for microprocessors
• Timing reference for communication interfaces
• System clock source for embedded controllers

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to guarantee proper solder joint formation during assembly.

Oscillators Selection Notes

Select this component when a precise 45.16 MHz timing source is required for low-voltage digital systems. The integrated enable function supports power-sensitive applications requiring dynamic clock gating. Consider the thermal characteristics and operating temperature range to ensure stability under the intended environmental conditions.

Oscillators Part Context

This model belongs to the Mercury Electronics standard XO series, which provides reliable frequency control solutions. The manufacturer specializes in quartz-based frequency products, including crystals and oscillators, serving various industrial and consumer electronics sectors with standardized form factors.

Oscillators Replacement Considerations

Direct substitutes must match the 45.16 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent electrical parameters such as phase noise and jitter specifications to maintain system timing integrity without redesigning the host circuitry.
