18QHTF21-2.097152-PD

Oscillators Overview

The 18QHTF21-2.097152-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 2.097152 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby and power-down functionality
• Provides standard LVCMOS output signals

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Low-power electronic circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 2.097152 MHz reference is required for low-power applications. The small 2.0x1.6 mm form factor makes it suitable for space-constrained designs. Consider the LVCMOS interface compatibility with your target microcontroller or FPGA inputs to ensure signal integrity without additional buffering.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 4-SMD package. The 'PD' suffix typically indicates the inclusion of a power-down control feature, allowing for energy savings when the oscillator is not actively needed in the application.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical pinouts but different frequencies, such as 18QHTF21-25.000-PD, if frequency adjustment is permissible. Cross-reference with similar 2.0x1.6mm LVCMOS oscillators from other manufacturers only if electrical parameters match exactly.
