18QHTF21-11.060472-PD

Overview

The 18QHTF21-11.060472-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 11.060472 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down standby function to reduce consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V for energy-efficient applications
• Includes a power-down standby mode to minimize current consumption when inactive
• Delivers standard LVCMOS output signals suitable for digital interfaces

Applications

• General-purpose clock generation in embedded systems
• Timing reference for microcontrollers requiring 11.06 MHz
• Consumer electronics utilizing low-profile surface-mount components

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail is stable and within the operational limits specified in the official datasheet. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 11.060472 MHz clock source is required in space-constrained designs. The choice is driven by the need for low voltage compatibility and the ability to disable the oscillator via standby mode. Consider the small form factor if board real estate is limited, while ensuring the LVCMOS interface aligns with the target logic family.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series is characterized by its small footprint and low voltage operation. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from continuous-operation variants within the same product line.

Replacement Considerations

Direct substitutes must match the 11.060472 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications before cross-referencing other manufacturers' offerings.
