18QHTF21-8.192-OE

Overview

The 18QHTF21-8.192-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 8.192 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. 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 enable/disable functionality for power management
• Utilizes a surface-mount 4-SMD no lead package design

Applications

• Clock signal generation in embedded systems
• Timing reference for microcontrollers
• Data communication interface synchronization

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 power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a precise 8.192 MHz timing source is required for low-voltage digital circuits. The LVCMOS output is suitable for direct interfacing with standard logic families. Consider the small form factor for space-constrained designs. Verify that the operating temperature range meets the environmental conditions of the intended application scenario.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The 'OE' suffix typically denotes the enable pin configuration. This family targets applications requiring reliable clock signals in portable and industrial electronics.

Replacement Considerations

Direct substitutes must match the 8.192 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as jitter and phase noise. Consult manufacturer cross-reference lists for equivalent parts from other suppliers offering identical specifications.
