18QHTF21-49.152-PD

Oscillators Overview

The 18QHTF21-49.152-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 49.152 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and incorporates a standby or power-down feature 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 low-voltage operation at 1.8V
• Includes standby mode capability
• Provides LVCMOS signal output

Oscillators Applications

• General electronic timing circuits
• Digital signal processing systems
• Communication equipment clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper assembly and electrical connectivity.

Oscillators Selection Notes

Select this component when a precise 49.152 MHz clock source is required for low-power applications. The choice is driven by the need for LVCMOS compatibility and a small form factor. Consider the standby feature if power conservation during idle states is a critical design parameter for the end product.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal oscillators. The manufacturer is a Taiwan-based supplier established in 1973, focusing on frequency control products including crystals, filters, and various oscillator types for industrial and consumer electronics markets.

Oscillators Replacement Considerations

Direct substitutes include other 49.152 MHz XO models from Mercury Electronics within the same series, such as the 18QHTF21-48.7056-PD or 18QHTF21-63.152-PD, provided the frequency difference is acceptable for the application.
