18QHTF21-16.369-PD

Oscillators Overview

The 18QHTF21-16.369-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 16.369 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes a power-down feature for standby mode control. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates power-down functionality for energy management
• Provides LVCMOS signal output compatibility

Oscillators Applications

• Digital clock signal generation
• Microcontroller system timing
• Communication interface synchronization

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 rail is stable within the operational range specified in the official datasheet. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a precise 16.369 MHz reference is required for low-power digital systems. The choice depends on the necessity for an integrated power-down capability to reduce standby current consumption. Evaluate the physical space constraints to ensure the 2.0x1.6 mm package fits the available board area without compromising thermal or mechanical reliability.

Oscillators Part Context

This model belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series is characterized by small form factors and standardized LVCMOS outputs. The suffix PD indicates the inclusion of a power-down pin for active control, distinguishing it from continuously running variants within the same product family.

Oscillators Replacement Considerations

Direct substitutes must match the 16.369 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility for the power-down function. Cross-reference with other manufacturers offering identical electrical specifications and mechanical dimensions to ensure seamless integration into existing designs.
