18QHTF21-11.100-PD

Overview

The 18QHTF21-11.100-PD is a 11.1 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and utilizes LVCMOS output logic. The component features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• LVCMOS output logic interface
• Standby (Power Down) functionality
• Compact 4-SMD surface mount package

Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific frequency suffix matches the required 11.1 MHz specification. Confirm the 1.8V supply voltage requirement aligns with the target circuit design. Ensure the 4-SMD package footprint corresponds to the PCB layout constraints. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a low-voltage 1.8V operation is required. Consider the small 2.0x1.6mm footprint for space-constrained designs. The LVCMOS output is suitable for standard digital logic interfaces. Verify that the standby feature meets power management needs.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized small outline package. The 'PD' suffix typically indicates the presence of a power-down or standby pin configuration.

Replacement Considerations

Direct substitutes must match the 11.1 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other manufacturers offering identical electrical and mechanical specifications.
