18QHTF21-62.8375-PD

Overview

The 18QHTF21-62.8375-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 62.8375 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down (Standby) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes power-down standby control functionality
• 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 applications utilizing LVCMOS interfaces

Procurement Notes

Verify the specific frequency suffix matches the required 62.8375 MHz specification. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the LVCMOS output type is compatible with the receiving logic inputs. Check that the 4-SMD package footprint fits the PCB layout constraints.

Selection Notes

Select this component when a precise 62.8375 MHz timing source is required within a low-voltage 1.8V environment. The choice is appropriate for designs necessitating LVCMOS signaling standards. Consider the physical size constraints of the 2.0x1.6mm package during board layout planning. Verify thermal operating range requirements against application conditions.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series typically offers various frequencies with LVCMOS outputs and 1.8V operation. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from models without standby control capabilities.

Replacement Considerations

Direct substitutes must match the 62.8375 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility if replacing with other manufacturers' equivalents. Ensure identical power-down control logic behavior.
