18QHTF21-62.210-PD

Overview

The 18QHTF21-62.210-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 62.21 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down control feature. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Features LVCMOS output logic for digital interfacing
• Includes power-down capability for energy management

Applications

• Digital signal processing systems
• Communication equipment requiring precise clocking
• Embedded systems with space constraints

Procurement Notes

Verify the specific datasheet from Mercury Electronic Ind. Co., Ltd. to confirm electrical characteristics and mechanical tolerances. Ensure compatibility with 1.8V logic levels and LVCMOS requirements. Check for any specific handling instructions related to the 4-SMD no-lead package during assembly.

Selection Notes

Select this component when a 62.21 MHz clock source is required in a minimal footprint. Consider the 1.8V supply constraint and the need for power-down functionality. Verify that the LVCMOS output matches the input requirements of the downstream circuitry.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and package options. The PD suffix indicates the inclusion of a power-down pin, distinguishing it from models without this control feature.

Replacement Considerations

Direct substitutes must match the 62.21 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics before substitution.
