18QHTF21-61.049-PD

Overview

The 18QHTF21-61.049-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 61.049 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications.

Feature Summary

• Supports low-voltage operation with 1.8V supply requirement
• Includes standby capability for power-down management
• Utilizes LVCMOS output logic for digital interface compatibility
• Employes a leadless SMD package for space-efficient mounting

Applications

• General-purpose clock signal generation
• Digital system timing references
• Embedded electronics requiring low-power 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 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 61.049 MHz reference is required with minimal power consumption. The LVCMOS output ensures compatibility with standard digital logic families. Consider the leadless package for high-density board designs where vertical space is limited. Validate thermal performance within the specified operating temperature range for your intended environment.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products.
