18QHTF21-119.01125-PD

Overview

The 18QHTF21-119.01125-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 119.01125 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 2.0x1.6 mm. This component is designed for applications requiring precise clock signals within space-constrained electronic systems.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby and power-down functionality to reduce power consumption
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• General-purpose clock signal generation
• Digital communication systems
• Embedded control circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your power architecture. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a stable 119.01125 MHz clock source is required in a minimal footprint. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the power-down feature if battery life or thermal management is a priority. Verify that the operating temperature range meets your environmental specifications.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a small form factor. The series is characterized by its use of LVCMOS outputs and support for low-voltage operation. Similar parts in the series include different frequency variants such as 96.768 MHz and 25.5625 MHz, all sharing the same physical package and logical interface.

Replacement Considerations

Direct substitutes must match the 119.01125 MHz frequency, LVCMOS output, and 1.8V supply. Compatible packages include 4-SMD no-lead types with identical 2.0x1.6 mm dimensions. Verify pinout compatibility and electrical characteristics before substitution.
