18QHTF21-47.39166-PD

Oscillators Overview

The 18QHTF21-47.39166-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a nominal frequency of 47.39166 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and supporting a standby or power-down mode. It is housed in a compact 4-SMD, no-lead package, suitable for surface-mount assembly in space-constrained electronic designs requiring precise timing signals.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby or power-down functionality for energy management
• Utilizes a 4-SMD no-lead surface-mount package design

Oscillators Applications

• General-purpose digital circuit timing
• Low-voltage embedded systems
• Portable electronic devices requiring power efficiency

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 4-SMD no-lead footprint matches the target PCB layout dimensions. Ensure the 1.8V supply rail stability meets the oscillator's noise sensitivity specifications to maintain signal integrity during operation.

Oscillators Selection Notes

Select this component when a 47.39166 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V supply constraint and the availability of standby control signals. Evaluate the thermal performance within the specified operating temperature range. Compare package dimensions against available board space to ensure mechanical fit for the 4-SMD no-lead configuration.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a manufacturer specializing in quartz crystals and oscillators. The series typically offers various frequency options within a standardized small form factor. The 'PD' suffix likely indicates the inclusion of power-down capabilities, distinguishing it from standard continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 47.39166 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if critical. Cross-reference with other Mercury Electronics models in the 18QHTF21 series for potential drop-in replacements.
