18QHTF21-13.496-PD

Overview

The 18QHTF21-13.496-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 13.496 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes Standby (Power Down) functionality to reduce power consumption
• Operates on a 1.8V supply voltage

Applications

• Battery-powered portable devices
• General-purpose clock signal generation
• Digital circuit timing reference

Procurement Notes

Verify the specific ordering suffix PD against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails before procurement. Ensure the 4-SMD no-lead footprint matches the PCB design guidelines.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS signaling. The integrated standby feature makes it suitable for systems requiring active power management. Verify that the 13.496 MHz frequency meets the precise timing requirements of the application compared to standard frequencies.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and oscillators. The series includes various frequencies such as 8.000 MHz and 51.200 MHz, all sharing similar package dimensions and electrical characteristics like the 1.8V supply and LVCMOS output.

Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with different frequencies, such as 18QHTF21-8.000-PD or 18QHTF21-51.200-PD, provided the frequency difference is acceptable for the application.
