18QHTF21-3.1152-PD

Oscillators Overview

The 18QHTF21-3.1152-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 3.1152 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component is engineered for precision timing applications requiring low power operation.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode functionality for power management
• Utilizes a small form factor surface-mount package

Oscillators Applications

• Portable electronic devices requiring precise clock signals
• Embedded systems with limited power budgets
• Communication modules needing stable frequency references

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions. Check for any specific handling instructions regarding electrostatic discharge during assembly.

Oscillators Selection Notes

Select this component when a low-voltage, small-footprint oscillator is required for 3.1152 MHz applications. Consider the LVCMOS output level compatibility with your target microcontroller or FPGA. Evaluate the power-down feature if battery life or thermal management is a critical constraint in the final product design.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-power crystal oscillators. The series typically offers various frequencies within a standardized 2.0x1.6 mm package. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants.

Oscillators Replacement Considerations

Direct replacements must match the 3.1152 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify that substitute parts support the same standby functionality. Cross-reference pinouts to ensure compatibility with existing PCB layouts.
