18QHTF21-36.480-PD

Oscillators Overview

The 18QHTF21-36.480-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 36.48 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby (power down) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Integrates a standby mode to reduce power consumption during idle periods
• Utilizes a lead-free surface-mount package for automated assembly

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail is stable within the operational limits specified in the official datasheet. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to guarantee proper soldering and mechanical stability during operation.

Oscillators Selection Notes

Select this component when a low-profile, lead-free oscillator is required for space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital circuits. Consider the standby feature if power efficiency is a critical design parameter. Verify compatibility with the host system's input logic levels and ensure the 36.48 MHz frequency aligns with the system clock requirements.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized 2.0x1.6mm package. The series provides options for different supply voltages and output types. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from standard continuous-operation variants within the same physical form factor family.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical 36.48 MHz frequency and 1.8V LVCMOS specifications. Cross-referencing with other manufacturers requires verifying pin compatibility, electrical parameters, and package dimensions to ensure functional equivalence without redesign.
