18QHTF21-61.736-PD

Overview

The 18QHTF21-61.736-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 61.736 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby power-down mode to reduce energy consumption during inactive periods. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

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

Applications

• General clock signal generation
• Digital system timing reference
• Embedded controller synchronization

Procurement Notes

Verify the specific ordering suffix PD against the manufacturer's current datasheet to ensure compatibility with required packaging and tape-and-reel specifications. Confirm that the 1.8V supply requirement aligns with the target circuit design before procurement.

Selection Notes

Select this component when a precise 61.736 MHz frequency is required within a space-constrained environment. The 1.8V operating voltage makes it suitable for modern low-power digital circuits. Ensure the LVCMOS output level matches the input requirements of the receiving logic gate.

Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series is characterized by small form factors and standardized pinouts. The 18 prefix typically indicates the 1.8V supply variant within this product family.

Replacement Considerations

Direct substitutes must match the 61.736 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package dimensions. Verify electrical parameters such as jitter and phase noise if strict timing performance is critical.
