18QHTF21-1.6384-PD

Overview

The 18QHTF21-1.6384-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 1.6384 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a power-down (standby) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes standby mode to reduce power consumption during idle periods
• Utilizes a leadless surface-mount package for space-constrained designs

Applications

• General-purpose timing reference in embedded systems
• Clock source for low-frequency microcontrollers
• Power-sensitive portable electronic devices

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 PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a precise 1.6384 MHz clock signal is required with minimal power usage. The LVCMOS interface ensures compatibility with standard logic families. Consider the small form factor if board real estate is limited. Verify operating temperature ranges if the application involves extreme environmental conditions beyond standard commercial grades.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a supplier specializing in quartz crystals and oscillators. The series offers various frequencies within a standardized 2.0x1.6mm package. This specific model provides a low-frequency option suitable for applications not requiring high-speed clocking but demanding reliability and low power.

Replacement Considerations

Direct substitutes must match the 1.6384 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Check datasheets for equivalent pinouts and electrical characteristics from other manufacturers offering similar timing solutions.
