18QHTF21-110.000-PD

Overview

The 18QHTF21-110.000-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 110 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm, designed for surface-mount applications.

Feature Summary

• Supports low voltage operation at 1.8V
• Includes standby and power-down functionality
• Utilizes LVCMOS output interface

Applications

• Battery-powered electronic devices
• Portable consumer electronics
• General-purpose digital signal processing systems

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 110 MHz clock source is required for LVCMOS-compatible circuits. The choice is driven by the need for low power consumption due to the 1.8V operation and the inclusion of a power-down feature for extended battery life in portable applications. The small 2.0x1.6 mm package size makes it suitable for space-constrained designs.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 2.0x1.6 mm SMD package. The series typically provides options for different supply voltages and output types, allowing designers to maintain consistent board layouts while adjusting electrical parameters for specific application needs across different product lines.

Replacement Considerations

Direct replacements must match the 110 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6 mm package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar ultra-small form factor oscillators if Mercury Electronics availability is limited.
