18QHTF21-61.965-PD

Overview

The 18QHTF21-61.965-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 61.965 MHz and utilizes LVCMOS output logic. The device is designed for low voltage applications, requiring a supply voltage of 1.8V. It features a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component includes a standby or power-down function to manage energy consumption during inactive periods.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Integrates a standby or power-down control function
• Utilizes a compact 4-SMD no lead surface mount package

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 1.8V operation
• Embedded devices utilizing standard LVCMOS interfaces

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Ensure that the PCB footprint matches the 2.0x1.6mm SMD package dimensions. Confirm that the 1.8V supply rail can provide sufficient current for the oscillator's startup and steady-state operation without voltage droop.

Selection Notes

Select this component when a precise 61.965 MHz timing source is required within space-constrained designs. The choice is driven by the need for a low-profile 4-SMD package and compatibility with 1.8V logic families. Consider the standby feature if power management is a critical design constraint for the target application environment.

Part Context

This part belongs to the 18QHTF series of crystal oscillators from Mercury Electronics. The series is characterized by small form factors and low voltage operation. Similar parts in the lineup vary primarily by frequency and package size, but share common electrical characteristics such as LVCMOS outputs and standby capabilities.

Replacement Considerations

Direct substitutes must match the 61.965 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and thermal performance before replacing.
