18QHTF21-59.9416-PD

Overview

The 18QHTF21-59.9416-PD is a 59.9416 MHz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates on a 1.8V supply voltage and features LVCMOS output logic. The component supports a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The unit exhibits a frequency stability of ±50ppm and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports low-voltage 1.8V operation with standby power-down capability
• Delivers standard LVCMOS output signals
• Maintains high frequency stability of ±50ppm
• Utilizes a compact 4-SMD no-lead surface-mount package

Applications

• Battery-powered portable electronic devices
• Communication systems requiring precise clock timing
• Embedded digital circuits needing low-power oscillators

Procurement Notes

Verify the specific suffix PD indicates strip packaging when sourcing. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD footprint aligns with the PCB layout specifications. Check that the ±50ppm stability meets system timing tolerances. Validate the -40°C to +85°C temperature range against environmental conditions.

Selection Notes

Select this model for applications demanding low voltage operation and small form factors. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the ±50ppm stability for general-purpose timing needs rather than high-precision references. The power-down feature makes it suitable for battery-constrained designs.

Part Context

This component belongs to the 18QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and compact packaging. The 18QHTF21 variant specifically targets space-constrained portable electronics requiring reliable clock generation.

Replacement Considerations

Cross-reference other 18QHTF21 series variants for different frequencies. Verify pinout and electrical characteristics match before substituting. Ensure alternative components support the same 1.8V supply and LVCMOS output requirements.
