18QHTF21-24.5762-PD

Oscillators Overview

The 18QHTF21-24.5762-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 24.5762 MHz and utilizes an LVCMOS output signal type. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption during inactive periods. The component is housed in a compact 4-SMD, no-lead package with dimensions of 2.00mm x 1.60mm.

Oscillators Feature Summary

• Supports LVCMOS output signal compatibility
• Includes standby and power-down functionality
• Operates on a 1.8V supply voltage

Oscillators Applications

• General electronic timing circuits
• Embedded systems requiring low-power oscillators
• Digital signal processing interfaces

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V operating voltage aligns with the system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 24.5762 MHz clock source is required with minimal power consumption. The integrated power-down feature makes it suitable for battery-operated devices. Ensure the application environment supports the standard XO performance characteristics and that the physical size constraints accommodate the 2.0x1.6mm package dimensions.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co. Ltd, a manufacturer specializing in quartz crystals and oscillators since 1973. The series typically offers various frequencies within a small surface-mount form factor. The 'PD' suffix indicates the inclusion of power-down capabilities, distinguishing it from standard continuous-operation variants within the same package family.

Oscillators Replacement Considerations

Direct substitutes must match the 24.5762 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators with standby functions to ensure electrical equivalence.
