18QHTF21-58.600-PD

Overview

The 18QHTF21-58.600-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a fixed frequency of 58.6 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and including a standby or power-down function to reduce energy consumption during idle periods. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode for power management efficiency
• Utilizes a small form factor SMD package for space-constrained designs

Applications

• General-purpose clock signal generation in embedded systems
• Timing reference sources for microcontrollers and processors
• Data communication interfaces requiring precise frequency standards

Procurement Notes

Verify the specific ordering suffix and frequency tolerance requirements against the official datasheet before procurement. Ensure that the 1.8V supply voltage aligns with the target system's power rails. Confirm the package type matches the PCB footprint design. Check for any specific environmental qualification requirements if operating in extreme conditions.

Selection Notes

Select this component when a low-voltage, low-power clock source is required for high-density circuits. The LVCMOS output ensures compatibility with standard digital logic families. Consider the physical size constraints of the application, as the 2.0x1.6mm package is optimized for miniaturization. Evaluate the need for power-down functionality to extend battery life in portable devices.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized small outline package. These components are engineered for reliability and stability in consumer electronics and industrial control applications where space and power efficiency are critical factors.

Replacement Considerations

Direct substitutes must match the 58.6 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications before substitution.
