18QHTF21-47.647-PD

Oscillators Overview

The 18QHTF21-47.647-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 47.647 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Features LVCMOS output logic compatibility
• Includes standby and power-down functionality

Oscillators Applications

• General-purpose digital clock generation
• Embedded system timing references
• Portable electronic devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure that the 1.8V supply rail is stable and within the specified operating range to maintain signal integrity. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions to avoid assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a precise 47.647 MHz reference is required with minimal power consumption. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the small form factor for space-constrained designs. Verify that the operating temperature range meets the environmental conditions of the intended application.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series offers various frequencies and voltage options, all sharing a common compact 2.0x1.6mm footprint. The 'PD' suffix indicates the inclusion of power-down capabilities, distinguishing it from standard continuous-operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 47.647 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Check equivalent models from other manufacturers ensuring identical pinout and mechanical dimensions to guarantee drop-in replacement capability without PCB redesign.
