18QHTF21-71.750-PD

Overview

The 18QHTF21-71.750-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 71.75 MHz with a supply voltage of 1.8V. The component utilizes LVCMOS output logic and features a Standby function for power management. It is housed in a 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports low voltage operation at 1.8V
• Includes standby mode for power reduction
• Utilizes standard LVCMOS output interface

Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a precise 71.75 MHz clock source is required within a compact form factor. The 1.8V operating voltage makes it suitable for modern low-power digital systems. Consider the standby feature if power efficiency is a critical design constraint. Verify compatibility with the host device's input logic levels and ensure the physical dimensions fit within the designated area on the printed circuit board.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies tailored for different digital applications. The 'PD' suffix typically indicates a specific packaging or tape-and-reel configuration. These components are designed for reliability in consumer electronics and industrial equipment requiring stable clock signals.

Replacement Considerations

Direct substitutes must match the 71.75 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Check datasheets for equivalent parts from other manufacturers ensuring identical pinout and electrical characteristics to maintain system functionality without redesign.
