18QHTF21-13.57325-PD

Overview

The 18QHTF21-13.57325-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.57325 MHz with a stability of 50 ppm. The device utilizes LVCMOS output logic and requires a 1.8V supply voltage. It features a Standby (Power Down) control function for power management. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports Standby (Power Down) mode for efficient power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Housed in a compact 4-SMD No Lead surface-mount package

Applications

• Portable electronic devices requiring low power consumption
• Communication systems utilizing standard clock signals
• Embedded controllers needing precise timing references

Procurement Notes

Verify the specific suffix 'PD' indicates the Standby (Power Down) feature rather than other variants like 'OE'. Confirm the operating temperature range and load capacitance requirements against the target system design. Ensure the 4-SMD No Lead footprint matches the PCB layout specifications to prevent assembly issues.

Selection Notes

Select this component when a 13.57325 MHz clock signal is required with strict power constraints. The 1.8V supply voltage suits modern low-voltage digital circuits. The Standby feature allows for active power saving during idle periods, making it suitable for battery-operated applications where energy efficiency is critical.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 18QHTF21 series is designed for general-purpose timing applications, providing reliable performance in consumer electronics and industrial equipment through standardized packaging and logic outputs.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical frequency and package but different control suffixes if standby functionality is not required. Cross-brand replacements must match the 2.0x1.6mm footprint, 1.8V supply, and LVCMOS output characteristics.
