18QHTF21-64.980-PD

Overview

The 18QHTF21-64.980-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 64.98 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and supports a standby or power-down mode for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Features LVCMOS output interface
• Includes standby and power-down functionality

Applications

• General clock signal generation
• Low-voltage digital circuits
• Embedded systems requiring stable timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail is stable to maintain oscillator performance. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a precise 64.98 MHz clock source is needed for LVCMOS-compatible devices. The 1.8V operating voltage makes it suitable for modern low-power applications. Consider the small 2.0x1.6mm package size for space-constrained designs. Evaluate the need for standby capabilities if power management is a priority in the system architecture.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a compact form factor. The 'PD' suffix indicates the inclusion of power-down functionality. These components are designed for high reliability in consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 64.98 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications before swapping. Consult manufacturer cross-reference lists for verified alternatives.
