18QHTF21-39.2832-PD

Oscillators Overview

The 18QHTF21-39.2832-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 39.2832 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features a Standby (Power Down) function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports Standby (Power Down) mode for reduced power consumption
• Utilizes LVCMOS output logic for digital interface compatibility
• Compact 4-SMD No Lead surface mount package design

Oscillators Applications

• Embedded systems requiring precise timing signals
• Digital communication interfaces
• Microcontroller clock sources

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and voltage configuration match the system requirements. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD No Lead footprint matches the PCB layout guidelines provided in the official datasheet to guarantee proper soldering and mechanical stability.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 39.2832 MHz frequency. The choice is driven by the need for a small form factor suitable for space-constrained designs. Consider the LVCMOS output level compatibility with the receiving logic gates. The standby feature is relevant if power efficiency during idle states is a critical design parameter.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, designed for general-purpose timing applications. It represents a standard fixed-frequency oscillator solution within the manufacturer's portfolio. The product line focuses on providing reliable quartz-based timing references in compact packages for modern electronic devices.

Oscillators Replacement Considerations

Direct substitutes must match the 39.2832 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and electrical specifications before swapping manufacturers.
