18QHTF21-65.767-PD

Overview

The 18QHTF21-65.767-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 65.767 MHz and utilizes LVCMOS output logic levels. The device requires a 1.8V supply voltage and supports a standby or power-down mode for energy management. It is housed in a compact 4-SMD, No Lead package designed for surface-mount assembly.

Feature Summary

• Supports low-voltage operation with a 1.8V supply requirement
• Integrates LVCMOS output interface for digital compatibility
• Includes standby functionality to reduce power consumption

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring LVCMOS interfaces
• Embedded applications necessitating low-power standby modes

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply rail stability matches the component specifications. Confirm that the 4-SMD No Lead package dimensions align with the target PCB footprint design constraints.

Selection Notes

Select this component when a precise 65.767 MHz timing source is required with low voltage operation. Consider the LVCMOS output compatibility with downstream logic families. Evaluate the need for standby capabilities to optimize system power efficiency during idle periods.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The 'PD' suffix typically indicates specific packaging or handling characteristics within the manufacturer's lineup.

Replacement Considerations

Direct substitutes must match the 65.767 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and electrical parameters such as phase noise and jitter if available in public documentation.
