18QHTF21-75.635-OE

Overview

The 18QHTF21-75.635-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 75.635 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features enable/disable control functionality. 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 digital interface compatibility
• Includes enable/disable pin control for power management
• Utilizes a surface-mount 4-SMD no-lead package design

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix against official Mercury Electronics documentation to ensure correct configuration. Confirm that the OE suffix aligns with the required enable/disable functionality and packaging specifications before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a 1.8V supply voltage is required for low-power applications. Ensure the host circuit supports LVCMOS logic levels. Verify that the 2.0x1.6mm footprint fits within the available PCB area. Check if enable/disable control is necessary for system power sequencing requirements.
