18QHTF21-65.000-PD

Overview

The 18QHTF21-65.000-PD is a 65 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and utilizes LVCMOS output logic. The component features an enable pin for control and supports a standby power-down mode to reduce consumption during inactivity. 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
• Includes enable pin functionality
• Features standby power-down mode

Applications

• Portable electronic devices requiring low power consumption
• Communication systems utilizing LVCMOS interfaces
• Embedded systems needing precise clock timing

Procurement Notes

Verify the specific suffix 'PD' against official Mercury Electronics documentation to confirm the presence of the power-down feature. Ensure the operating temperature range and load capacitance requirements match your circuit design specifications before finalizing procurement orders.

Selection Notes

Select this component when a small form factor is required alongside low-power standby capabilities. The 1.8V supply voltage makes it suitable for modern low-voltage digital circuits. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs of your target application.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequency options within a standardized 2.0x1.6 mm footprint. The 'PD' suffix typically denotes specific functional characteristics such as power-down support, distinguishing it from standard variants.

Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with matching frequencies and 1.8V LVCMOS outputs. Verify pin compatibility and electrical parameters carefully when considering alternatives from different manufacturers.
