18QHTF21-15.700-PD

Oscillators Overview

The 18QHTF21-15.700-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 15.7 MHz and utilizes LVCMOS output logic levels. The device requires a 1.8V supply voltage and includes a standby or power-down control feature for energy management. It is housed in a compact 4-SMD, no-lead package designed for surface-mount assembly.

Oscillators Feature Summary

• Supports low-voltage operation with a 1.8V supply requirement
• Integrates standby functionality for power reduction
• Provides LVCMOS output signal compatibility

Oscillators Applications

• General-purpose clock generation in embedded systems
• Timing reference for digital communication interfaces
• Power-sensitive portable electronic devices

Oscillators Procurement Notes

Verify the specific datasheet from Mercury Electronic Ind. Co., Ltd. to confirm electrical tolerances and thermal characteristics. Ensure the 1.8V supply rail stability meets the oscillator requirements. Confirm the 4-SMD package footprint matches the PCB design guidelines before finalizing procurement.

Oscillators Selection Notes

Select this component when a 15.7 MHz timing source is required with low power consumption constraints. The 1.8V operating voltage makes it suitable for modern low-power digital circuits. The integrated power-down feature supports applications requiring active and inactive states.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies while maintaining consistent package dimensions and electrical interface standards. The 'PD' suffix indicates the inclusion of a power-down control pin.
