18QHTF21-22.400-PD

Oscillators Overview

The 18QHTF21-22.400-PD is a 22.4 MHz crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a supply voltage of 1.8V and features an LVCMOS output signal. The component supports a Standby (Power Down) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby power-down capability
• Provides standard LVCMOS output signals

Oscillators Applications

• Embedded systems requiring precise timing
• Portable electronic devices utilizing low-power components
• Communication modules needing stable clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to avoid assembly issues.

Oscillators Selection Notes

Select this component when a small form factor and low power consumption are critical. The 1.8V operating voltage makes it suitable for battery-powered applications. Verify compatibility with microcontrollers or processors that accept LVCMOS inputs at the specified frequency.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6 mm package. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from continuous-output variants.

Oscillators Replacement Considerations

Direct replacements must match the 22.4 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check datasheets for equivalent parts from other manufacturers offering identical pinouts and electrical characteristics to ensure seamless integration.
