18QHTF21-28.6363-PD

Oscillators Overview

The 18QHTF21-28.6363-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 28.6363 MHz with LVCMOS output logic and a supply voltage of 1.8V. The device features a standby (power down) function and is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports low voltage operation at 1.8V for energy efficiency
• Includes standby mode to reduce power consumption when inactive
• Utilizes LVCMOS output logic for standard digital interface compatibility

Oscillators Applications

• General purpose clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interfaces requiring precise clock synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific handling instructions related to surface mount assembly processes.

Oscillators Selection Notes

Select this component when a small form factor is required alongside low power consumption. The 1.8V operating voltage makes it suitable for modern portable and battery-powered devices. Consider the LVCMOS output level if interfacing directly with standard logic families without additional buffering. The integrated power-down feature adds flexibility for power management strategies.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface mount oscillators from Mercury Electronics. The series offers various frequencies and packages, catering to diverse timing needs in consumer electronics and industrial applications. The 'PD' suffix indicates the inclusion of a power-down control pin or functionality.

Oscillators Replacement Considerations

Direct replacements must match the 28.6363 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package size. Verify pinout compatibility and electrical specifications such as jitter and stability before substituting.
