18QHTF21-94.800-PD

Overview

The 18QHTF21-94.800-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 94.8 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. It includes a standby (power down) control function for energy management.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby control functionality to reduce power consumption
• Utilizes a leadless surface-mount package design

Applications

• General purpose clock signal generation in electronic circuits
• Timing reference sources for embedded systems
• Digital communication equipment requiring stable frequency standards

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 avoid assembly issues during manufacturing.

Selection Notes

Select this component when a precise 94.8 MHz timing source is required within a low-voltage environment. Consider the physical size constraints of the 2.0x1.6 mm package for dense board layouts. Evaluate the need for standby functionality if power efficiency is a critical design parameter for the target application.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies while maintaining consistent electrical characteristics and package dimensions. It serves as a standardized timing solution for applications requiring reliable quartz-based frequency generation in compact form factors.

Replacement Considerations

Direct substitutes must match the 94.8 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar SMD oscillators ensuring identical electrical parameters and mechanical footprint.
