18QHTF21-13.9513-PD

Oscillators Overview

The 18QHTF21-13.9513-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 13.9513 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm, suitable for space-constrained surface-mount applications.

Oscillators Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Supports standby mode via power-down control signal
• Utilizes a leadless SMD package for automated surface-mount assembly

Oscillators Applications

• General-purpose timing clock generation in embedded systems
• Synchronization sources for digital communication interfaces
• Clock reference for microcontrollers and processors requiring low-voltage operation

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's operating specifications. Ensure the PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package dimensions to guarantee proper solder joint formation and mechanical reliability during assembly.

Oscillators Selection Notes

Select this component when a precise 13.9513 MHz reference is required with low-power standby capabilities. The LVCMOS output ensures direct interfacing with standard logic families without additional level shifting. Consider the small form factor for dense board layouts where larger packages are impractical. Validate thermal performance within the specified operating temperature range for the intended environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series offers various frequencies and voltage options, all sharing a common compact 4-SMD no-lead package profile. The 'PD' suffix indicates the inclusion of a power-down pin for standby functionality, distinguishing it from non-pd variants within the same physical footprint family.
