18QHTF21-28.200-PD

Oscillators Overview

The 18QHTF21-28.200-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a fixed frequency of 28.2 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down function via a standby control input. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down capability for energy management
• Provides LVCMOS digital output signals
• Utilizes a small form-factor surface-mount package

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring low voltage
• Embedded devices utilizing surface-mount technology

Oscillators Procurement Notes

Verify the specific frequency tolerance and phase noise specifications against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues.

Oscillators Selection Notes

Select this component when a precise 28.2 MHz timing source is required within a low-power environment. The choice depends on the necessity for a power-down feature to extend battery life or reduce thermal load. The small footprint makes it suitable for space-constrained printed circuit board layouts.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies while maintaining consistent electrical characteristics and physical dimensions. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants.

Oscillators Replacement Considerations

Direct substitutes must match the 28.2 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical parameters before swapping. Generic replacements may lack the specific power-down functionality.
