18QHTF21-60.0003-PD

Overview

The 18QHTF21-60.0003-PD is a 60.0003 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It utilizes LVCMOS output logic and operates on a 1.8V supply voltage. The device features a Standby (Power Down) control function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for standard clock applications requiring precise frequency generation.

Feature Summary

• LVCMOS output logic interface
• Standby power down capability
• Compact 4-SMD surface mount package

Applications

• Battery-powered portable devices
• General digital clock signal generation
• Standard electronic circuit timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific RoHS or lead-free compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small form factor. The LVCMOS output is suitable for direct interfacing with standard CMOS logic families. Consider the standby feature if power conservation during idle states is a priority. Verify that the 60.0003 MHz frequency meets the exact timing needs of the application.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a standardized 2.0x1.6mm package. The '-PD' suffix indicates the inclusion of a power-down pin or functionality, distinguishing it from non-stanby variants in the same physical footprint family.

Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators in a 2.0x1.6mm 4-SMD package with a 60.0003 MHz frequency. Ensure compatible output drive strength and rise/fall times. Verify that alternative parts also support the standby control function if power management is critical to the design.
