18QHTF21-71.220-PD

Overview

The 18QHTF21-71.220-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 71.22 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm. This component is designed for applications requiring precise timing signals within a small form factor.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Supports standby mode to reduce power consumption during inactive periods
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation in electronic circuits
• Timing reference for digital systems requiring 71.22 MHz stability
• Embedded devices utilizing low-voltage 1.8V logic families

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no-lead package footprint matches the PCB layout requirements. Check for any specific handling instructions related to the surface mount technology used in this component.

Selection Notes

Select this oscillator when a fixed 71.22 MHz frequency is required with LVCMOS outputs. Consider the 1.8V supply constraint and the availability of standby functionality for power-sensitive designs. Evaluate the physical space constraints given the 2.0 x 1.6 mm package size. Compare performance metrics such as phase noise and stability if available in the manufacturer documentation.
