18QHTF21-75.605-OE

Overview

The 18QHTF21-75.605-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 75.605 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features an enable/disable control function. It is housed in a compact 4-SMD, no lead package suitable for surface mount applications.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable/disable functionality for power management
• Designed as a standard XO with quartz-based frequency stability

Applications

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

Procurement Notes

Verify the exact frequency suffix matches the required 75.605 MHz specification, as similar part numbers exist with different frequencies such as 75.630 MHz or 86.8875 MHz. Confirm the 1.8V supply requirement aligns with the target system design. Ensure the 4-SMD no lead package footprint is compatible with the PCB layout. Check datasheet specifications for operating temperature range and load capacitance requirements before finalizing procurement.

Selection Notes

Select this component when a low-voltage 1.8V LVCMOS clock source is required. The enable/disable feature allows for dynamic power control in battery-operated devices. The small 4-SMD form factor is ideal for space-constrained designs. Verify that the specific 75.605 MHz frequency is available from Mercury Electronics, as other variants in the series offer different frequencies.

Part Context

This oscillator belongs to the Mercury Electronics 18QHTF21 series, which includes various standard XO models with different frequency options.
