18QHTF21-4.0625-OE

Oscillators Overview

The 18QHTF21-4.0625-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 4.0625 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated enable/disable pin for power control
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose digital timing circuits
• Embedded systems requiring low-voltage clock sources
• Consumer electronics with space constraints

Oscillators Procurement Notes

Verify the specific suffix 'OE' indicates the enable function as documented. Confirm RoHS compliance status through official manufacturer declarations or authorized distributor datasheets. Ensure the 1.8V supply requirement matches the target circuit design before procurement.

Oscillators Selection Notes

Select this component when a 4.0625 MHz clock signal is required with LVCMOS compatibility. The 1.8V operating voltage dictates suitability for low-power designs. The 4-SMD package size should be evaluated against PCB layout constraints compared to larger oscillator packages.

Oscillators Part Context
