18QHTF21-6.4512-PD

Overview

The 18QHTF21-6.4512-PD is a crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 6.4512 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and features a power-down standby function. It is housed in a 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down standby capability
• Utilizes LVCMOS output logic

Applications

• Battery-powered devices
• Portable electronics

Procurement Notes

Verify the specific manufacturer documentation for the 18QHTF21-6.4512-PD to confirm electrical characteristics and mechanical tolerances. Ensure compatibility with system voltage levels and interface requirements before integration. Cross-reference official datasheets for precise operating conditions and environmental specifications.

Selection Notes

Select this component for applications requiring a 6.4512 MHz clock signal with low power consumption. The 1.8V supply and compact 2.0x1.6mm package suit space-constrained designs. Confirm that the LVCMOS output aligns with the target circuit's input logic thresholds.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from standard continuous-operation variants.

Replacement Considerations

Direct substitutes must match the 6.4512 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm footprint. Verify pinout compatibility and electrical parameters against the original datasheet.
