18QHTF21-47.000-OE

Oscillators Overview

The 18QHTF21-47.000-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 47.0 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for power management
• Utilizes a lead-free SMD package for surface mount assembly

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 47 MHz
• Embedded applications utilizing 1.8V logic levels

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's power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper mechanical fit and electrical connection during assembly.

Oscillators Selection Notes

Select this component when a precise 47.0 MHz timing source is required within a low-voltage 1.8V environment. The choice is driven by the need for LVCMOS compatibility and the physical constraints of the 2.0x1.6mm package. Consider the enable pin feature if dynamic power control is necessary for the application's operational modes.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltages, all sharing the same compact 4-SMD form factor. The 'OE' suffix typically denotes specific packaging or tape-and-reel options as defined by the manufacturer's ordering nomenclature.

Oscillators Replacement Considerations

Direct substitutes must match the 47.0 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package dimensions. Verify equivalent electrical parameters such as phase noise and stability before substitution.
