18QHTF21-6.0053-PD

Overview

The 18QHTF21-6.0053-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 6.0053 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm. The component is designed for standard clock signal generation applications requiring precise timing.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Includes standby mode functionality to reduce power consumption during idle periods
• Utilizes quartz crystal technology for stable frequency generation

Applications

• General clock signal generation in electronic circuits
• Timing reference sources for digital systems
• Embedded devices requiring low-power oscillators

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout specifications. Check for any specific operating temperature range limitations defined in the official datasheet for your application environment.

Selection Notes

Select this component when a low-profile 2.0x1.6 mm oscillator is required for space-constrained designs. The 1.8V supply voltage makes it suitable for modern low-voltage digital logic families. Consider the standby feature if power efficiency is a critical design parameter. Ensure the LVCMOS output swing is compatible with the input thresholds of the receiving logic gates in your system architecture.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages within a standardized small outline package. The 'PD' suffix likely indicates the inclusion of a power-down control pin or function, distinguishing it from basic continuous-operation variants within the same physical form factor.

Replacement Considerations

Direct substitutes must match the 6.0053 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility, particularly regarding the standby/power-down control if applicable. Cross-reference with other manufacturers offering similar low-profile SMD oscillators with identical electrical characteristics and thermal ratings.
