18QHTF21-12.8832-PD

Overview

The 18QHTF21-12.8832-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 12.8832 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a standby power-down mode for energy efficiency. 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
• Compact surface-mount package design

Applications

• Portable electronic devices requiring low power consumption
• Embedded systems utilizing LVCMOS interfaces
• Communication modules needing precise timing signals
• Consumer electronics with space constraints

Procurement Notes

Verify the specific suffix PD indicates the power-down feature against official datasheets. Confirm the operating temperature range and load capacitance requirements match the target circuit design. Ensure the 4-SMD no-lead package footprint aligns with PCB layout specifications to prevent soldering issues during assembly.

Selection Notes

Select this component when a 12.8832 MHz clock signal is required with minimal power usage. The 1.8V supply requirement suits modern low-voltage digital circuits. Consider the physical size constraints due to the small 2.0x1.6 mm package. Evaluate thermal performance if the application involves high ambient temperatures or dense board layouts.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, designed for general-purpose timing applications. The series offers various frequencies and supply voltages. The PD suffix specifically denotes the inclusion of a power-down control pin, distinguishing it from standard continuous-operation variants within the same family.

Replacement Considerations

Check for direct substitutes with identical 12.8832 MHz frequency, 1.8V supply, and LVCMOS output. Verify that alternative components support the same 4-SMD no-lead package dimensions. Ensure compatible power-down functionality if low-power management is critical for the system design.
