18QHTF21-65.300-PD

Overview

The 18QHTF21-65.300-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 65.3 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby power-down mode. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

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

Applications

• General clock signal generation in electronic circuits
• Low-voltage digital system timing references
• Portable devices requiring power-efficient oscillators

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 rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 65.3 MHz reference is required for LVCMOS-compatible digital logic. The choice is driven by the need for a low-profile surface-mount solution and integrated power management features. Consider the operating temperature range and stability specifications relative to the environmental conditions of the intended application environment.
