18QHTF57-15.900-PD

Oscillators Overview

The 18QHTF57-15.900-PD is a 15.9 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and features an LVCMOS output signal. The component utilizes a 4-SMD, No Lead package with dimensions of 7.0x5.0 mm. A key functional characteristic is the inclusion of a Power Down (PD) pin, which enables standby mode to reduce power consumption when the device is not in active use.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V for energy-efficient system integration
• Integrates a dedicated Power Down pin to enable standby mode control
• Provides stable LVCMOS output signals for digital circuit synchronization

Oscillators Applications

• General-purpose clock generation in embedded systems
• Timing reference sources for communication interfaces
• Power-sensitive portable electronic devices requiring standby capabilities

Oscillators Procurement Notes

Verify that the specific part number matches the required frequency and voltage specifications before ordering. Confirm that the 4-SMD No Lead package dimensions align with the target PCB footprint. Ensure the design supports the LVCMOS logic levels and includes necessary pull-up or termination resistors if specified by the application requirements.

Oscillators Selection Notes

Select this component when a precise 15.9 MHz timing source is required alongside power management flexibility. The integrated power-down feature makes it suitable for applications where battery life or thermal management is critical. Ensure the host circuitry can accommodate the 1.8V operating range and the physical constraints of the small surface-mount package.

Oscillators Part Context

This oscillator belongs to the 18QHTF57 series from Mercury Electronics, designed for compact electronics. The series typically offers standard frequencies with low-power options. The 'PD' suffix indicates the presence of a power-down control function, distinguishing it from standard continuous-operation oscillators within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 15.9 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 7.0x5.0mm package. Verify compatibility of the power-down pin functionality if present in alternative parts.
