18QHTF21-10.00001-OE

Overview

The 18QHTF21-10.00001-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.00001 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and includes Enable/Disable functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports surface mount mounting type and is designed for standard timing applications requiring precise clock signals.

Feature Summary

• LVCMOS output interface for digital circuit compatibility
• Integrated Enable/Disable control for power optimization
• Compact 4-SMD no-lead surface mount package design

Applications

• General purpose clock signal generation
• Digital system timing reference
• Embedded controller clock input

Procurement Notes

Verify the exact frequency specification of 10.00001 MHz against application requirements, as standard variants typically use integer frequencies like 10.000 MHz. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 2.0x1.6mm footprint matches the PCB layout. Check for RoHS compliance if required by project specifications. Validate the LVCMOS output swing with downstream logic inputs.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific non-standard frequency of 10.00001 MHz. Consider the small 2.0x1.6mm package size for space-constrained designs. The Enable/Disable feature is beneficial for battery-powered or power-sensitive applications. Compare against other Mercury 18QHT series parts if standard 10MHz frequencies are acceptable, which may offer broader availability.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which features 4-SMD no-lead oscillators. The series typically offers various frequencies with LVCMOS outputs and 1.8V supply options. Similar parts in the database include models with frequencies such as 10.18 MHz, 21.2 MHz, and 37.888 MHz, all sharing the same package and electrical characteristics.

Replacement Considerations

Direct substitutes within the same series include 18QHTF21-10.180-OE for 10.18 MHz applications. For standard 10 MHz needs, verify if 18QHTF21-10.000-OE is available. Cross-reference with other manufacturers' 1.8V LVCMOS SMD oscillators in 2.0x1.6mm packages if Mercury stock is unavailable.
