18QHTF21-13.275-PD

Overview

The 18QHTF21-13.275-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.275 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a 1.8V supply voltage requirement. A key functional characteristic is the inclusion of a standby mode, allowing for power-down capabilities when the oscillator is not in active use. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes in electronic circuits requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features a standby function to enable power-down states
• Operates on a single 1.8V supply voltage rail

Applications

• Digital signal processing systems requiring clock synchronization
• Embedded controllers needing low-voltage timing references
• Portable electronics utilizing surface-mount components

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power architecture. Ensure the 4-SMD no-lead package dimensions fit within the designated PCB footprint constraints. Check for any specific handling instructions regarding electrostatic discharge protection during installation.

Selection Notes

Select this model when a stable 13.275 MHz reference is required with minimal power consumption. The LVCMOS output ensures direct interfacing with standard digital logic families without additional level shifting. The standby feature makes it suitable for battery-operated devices where power management is critical. Consider the operating temperature range specifications to ensure reliability under expected environmental conditions.

Part Context

This oscillator belongs to the Mercury Electronics 18QHTF series, which focuses on low-profile surface-mount solutions. The series typically offers various frequency options within a standardized package form factor. Mercury Electronics leverages its expertise in quartz crystal manufacturing to provide reliable frequency control products.
