18QHTF21-12.609375-PD

Overview

The 18QHTF21-12.609375-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 12.609375 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a standby power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby power-down capability
• Utilizes LVCMOS output interface

Applications

• Digital signal processing circuits
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the specific suffix PD indicates the power-down feature when sourcing. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD no-lead package footprint aligns with the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when a precise 12.609375 MHz reference is required with low power consumption capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the physical dimensions of the 4-SMD package during mechanical integration planning.

Part Context
