18QHTF21-11.130-PD

Overview

The 18QHTF21-11.130-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 11.13 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby power-down mode to minimize energy consumption during inactivity. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm, suitable for space-constrained surface-mount designs.

Feature Summary

• Supports low-voltage operation at 1.8V with integrated standby functionality
• Provides stable LVCMOS clock signals for digital circuit synchronization
• Utilizes a miniature 4-SMD no-lead footprint for efficient board layout

Applications

• Portable electronic devices requiring low-power clock sources
• Embedded systems utilizing LVCMOS-compatible processors
• Consumer electronics with strict size limitations

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD package dimensions fit within your PCB silkscreen and assembly constraints. Cross-reference the part number suffix with official documentation to confirm the exact operating specifications.

Selection Notes

Select this component when a precise 11.13 MHz reference is required for LVCMOS interfaces. Consider the 1.8V supply constraint and the availability of a power-down feature for battery-operated applications. Evaluate the 2.0x1.6 mm package size against available board real estate. Compare performance metrics such as phase noise and stability if high-precision timing is critical for the application.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series includes various frequencies and voltage options, all sharing the same compact SMD form factor. Mercury Electronics has decades of experience in manufacturing crystals and oscillators, positioning this part within their standard XO lineup for general-purpose timing needs.

Replacement Considerations

Direct substitutes must match the 11.13 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics before swapping manufacturers.
