18QHTF21-22.5792-PD

Oscillators Overview

The 18QHTF21-22.5792-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 22.5792 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby power-down mode. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports RoHS compliance standards.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby power-down functionality to reduce consumption
• Utilizes a compact 4-SMD no-lead surface mount package

Oscillators Applications

• General clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Portable electronic devices requiring small form factors

Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD package footprint matches the PCB layout requirements. Check for RoHS compliance documentation if environmental regulations apply to the final product assembly.

Oscillators Selection Notes

Select this component when a precise 22.5792 MHz timing source is required for LVCMOS-compatible logic families. The choice is driven by the need for a low-profile 2.0x1.6mm package and 1.8V operation. Consider the standby feature if power management during idle states is critical. Validate that the manufacturer's specifications meet the thermal and electrical constraints of the application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a standardized 1.8V LVCMOS format. The 'PD' suffix indicates the inclusion of a power-down control pin or function. These components are designed for high-volume manufacturing in consumer and industrial electronics where space and power efficiency are prioritized over ultra-high stability.

Oscillators Replacement Considerations

Direct substitutes must match the 22.5792 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and functional equivalence regarding the power-down feature. Cross-reference with other manufacturers offering similar low-profile XO solutions.
