18QHTF21-24.0024-PD

Oscillators Overview

The 18QHTF21-24.0024-PD is a 24.0024 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It utilizes LVCMOS output logic and operates on a 1.8V supply voltage. The component features a Standby (Power Down) function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• LVCMOS output interface
• Standby (Power Down) capability
• Compact 4-SMD No Lead package

Oscillators Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm 4-SMD No Lead package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output interface. The integrated standby feature makes it suitable for applications requiring power efficiency. The small form factor is ideal for space-constrained designs where a 2.0x1.6mm footprint is permissible. Consider the operating temperature range if the device will be used in extreme environmental conditions.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various standard frequencies within a small SMD package. The 'PD' suffix indicates the inclusion of a power-down control pin or functionality, distinguishing it from non-standby variants in the same physical package family.

Oscillators Replacement Considerations

Direct replacements must match the 24.0024 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility, specifically the power-down control configuration. Alternative parts from other manufacturers require careful evaluation of electrical parameters and thermal characteristics to ensure functional equivalence.
