18QHTF21-76.193-OE

Overview

The 18QHTF21-76.193-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 76.193 MHz. It utilizes LVCMOS output logic and supports a supply voltage range typically associated with its 1.8V enable/disable control feature. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This surface-mount device is designed for precise timing applications requiring low power consumption and reliable clock signal generation in space-constrained electronic circuits.

Feature Summary

• Integrates LVCMOS output logic for direct interface with digital systems
• Features 1.8V enable and disable control for power management
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• Portable consumer electronics requiring precise clock signals
• Communication modules needing stable frequency references
• Embedded systems with limited board space constraints

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V enable pin logic levels match your system's control voltages. Ensure the 4-SMD footprint matches your PCB layout guidelines to prevent assembly issues during manufacturing.

Selection Notes

Select this oscillator when a 76.193 MHz reference is required in a minimal footprint. Consider the LVCMOS output compatibility with your target microcontroller or FPGA. Evaluate the power consumption benefits of the enable/disable feature against your battery life requirements for portable devices.
