18QHTF21-8.0002-PD

Overview

The 18QHTF21-8.0002-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 8.0 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic for digital interfacing
• Includes Standby or Power Down functionality to reduce power consumption
• Utilizes a surface-mount 4-SMD no-lead package for automated assembly

Applications

• General clock signal generation for embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring compact oscillators

Procurement Notes

Verify the specific suffix 'PD' against the manufacturer's official documentation to confirm the presence of the Standby/Power Down pin configuration. Ensure the operating voltage requirements align with the 1.8V specification before integration into the target circuit design.

Selection Notes

Select this component when a small footprint 2.0x1.6 mm oscillator is required for 1.8V logic systems. The choice depends on the necessity for a power-down feature to manage standby currents in portable or battery-operated applications.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series includes various frequencies and packages, with this specific model focusing on the 8.0 MHz standard frequency variant.

Replacement Considerations

Direct substitutes include other 8.0 MHz LVCMOS oscillators in a 4-SMD 2.0x1.6mm package with 1.8V operation and standby capabilities. Verify pinout compatibility and electrical specifications before substitution.
