18QHTF21-29.800-PD

Oscillators Overview

The 18QHTF21-29.800-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 29.8 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a standby or power-down mode for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm. This component is designed for surface-mount applications requiring precise clock signals.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Includes standby and power-down functionality to reduce power consumption
• Utilizes a small form-factor 4-SMD no-lead package for space-constrained designs

Oscillators Applications

• Digital signal processing systems requiring precise timing references
• Communication equipment utilizing standard clock frequencies
• Embedded systems with strict power management requirements

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 PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package specifications. Check for any additional environmental ratings if operating in extreme temperatures. Always refer to the official datasheet for final electrical characteristics.

Oscillators Selection Notes

Select this model when a 29.8 MHz clock source is required with low power consumption capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the small package size for high-density board layouts. Verify that the operating temperature range meets your application's environmental conditions. Compare alternative frequencies if the exact 29.8 MHz is not strictly necessary.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various standard frequencies. The series typically includes models like 80.000-PD and 51.200-PD, sharing similar packaging and voltage characteristics. The 'PD' suffix indicates the inclusion of power-down functionality. These oscillators are designed for general-purpose timing applications in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes include other 29.8 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Ensure the replacement maintains the 1.8V supply requirement and identical pinout. Verify that the new component supports the same standby mode functionality. Check dimensional tolerances to ensure fit within the existing PCB footprint.
