18QHTF21-12.1496-OE

Overview

The 18QHTF21-12.1496-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 12.1496 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features an enable/disable control capability and is housed in a compact 4-SMD, No Lead package. This component is designed for surface mount applications.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable and disable functionality for power management
• Utilizes a leadless SMD package for surface mount assembly

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 1.8V operation
• Embedded devices utilizing standard crystal oscillator interfaces

Procurement Notes

Verify the specific frequency suffix (12.1496) against system requirements to ensure accurate timing. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD No Lead package footprint matches the PCB layout constraints. Check availability status as inventory levels may fluctuate.

Selection Notes

Select this model when a precise 12.1496 MHz clock source is required within a low-voltage 1.8V environment. Consider the enable/disable feature if power efficiency during idle states is critical. Verify that the LVCMOS output swing is compatible with downstream logic inputs without additional level shifting.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The 'OE' suffix likely denotes a specific packaging or tape-and-reel configuration compared to other variants like 'PD'.

Replacement Considerations

Direct substitutes include other 12.1496 MHz LVCMOS oscillators in a 4-SMD No Lead package with 1.8V operation. Verify pinout compatibility and electrical specifications before swapping. Cross-reference with similar Mercury Electronics models such as the 18QHTF21-12.1496-PD if package differences are acceptable.
