18QHTF21-46.080-PD

Oscillators Overview

The 18QHTF21-46.080-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 46.08 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features a power-down (PD) function to manage standby power consumption effectively. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for space-constrained surface-mount designs.

Oscillators Feature Summary

• Supports LVCMOS output logic for standard digital interface compatibility
• Includes power-down functionality for reduced standby current consumption
• Utilizes a compact 2.0x1.6 mm SMD package for efficient board space utilization

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Cross-reference the datasheet for operating temperature range specifications to guarantee reliability under intended environmental conditions.

Oscillators Selection Notes

Select this component when a 46.08 MHz clock source is required with low voltage operation. The LVCMOS output ensures compatibility with standard logic families. The integrated power-down feature makes it suitable for battery-operated or energy-efficient devices. The small form factor supports high-density assembly processes common in modern consumer electronics.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies while maintaining consistent electrical characteristics and physical dimensions. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants within the same package family.

Oscillators Replacement Considerations

Direct replacements must match the 46.08 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6 mm package. Verify pinout compatibility for the power-down function. Alternative parts from other manufacturers require careful evaluation of timing parameters and thermal performance.
