18QHTF21-13.255-PD

Overview

The 18QHTF21-13.255-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.255 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby or power-down functionality to reduce power consumption
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• General clock signal generation in electronic circuits
• Timing reference for low-voltage digital systems
• Portable devices requiring power-efficient oscillators

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet for your application environment.

Selection Notes

Select this component when a precise 13.255 MHz timing source is required with low voltage operation. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the small form factor if space is limited on the printed circuit board. Verify that the standby feature meets your power management strategy for battery-operated or energy-sensitive applications.

Part Context

This part belongs to the Mercury Electronics XO series, which offers various frequencies and packages. The 'PD' suffix typically indicates the inclusion of a power-down or standby control pin. Mercury Electronics specializes in quartz-based frequency control products, including crystals, oscillators, and filters, serving industries requiring reliable timing solutions.

Replacement Considerations

Direct replacements must match the 13.255 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify electrical parameters such as phase noise and jitter if critical. Ensure the replacement part also supports the standby function if used in the original design.
