18QHTF21-114.000-PD

Overview

The 18QHTF21-114.000-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 114.000 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• LVCMOS output logic for standard digital interface compatibility
• Integrated standby mode to reduce power consumption during idle periods
• Compact surface-mount package design suitable for space-constrained PCB layouts

Applications

• General clock signal generation for embedded systems
• Data communication interfaces requiring stable timing references
• Consumer electronics devices utilizing low-voltage logic circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your board layout specifications. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a precise 114 MHz clock source is needed in a minimal footprint. The LVCMOS output ensures direct interfacing with most modern microcontrollers and FPGAs without additional level shifting. The power-down feature makes it suitable for battery-operated applications where standby current reduction is critical.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-voltage, small-footprint oscillators. The series typically offers various frequencies within a standardized 2.0x1.6mm package. It is designed to replace larger through-hole or older surface-mount oscillators in modern portable and industrial electronics.

Replacement Considerations

Direct substitutes must match the 114.000 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if performance-critical.
