18QHTF21-48.461-PD

Oscillators Overview

The 18QHTF21-48.461-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 48.461 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and features a power-down (standby) function to reduce consumption when inactive. It is housed in a compact 4-SMD, No Lead surface-mount package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby mode for power management
• Utilizes LVCMOS signal interface

Oscillators Applications

• General digital circuit timing
• Embedded system clock generation
• Communication module synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before ordering. Confirm that the 1.8V operating voltage aligns with the system 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 48.461 MHz reference is required for 1.8V logic systems. Consider the LVCMOS output compatibility with downstream integrated circuits. Evaluate the need for the standby feature if power efficiency is critical. Compare physical size constraints against alternative packages to ensure the 2.0x1.6mm form factor fits the available board space.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The manufacturer specializes in quartz crystals, oscillators, and filters. This specific model represents a surface-mount option within their portfolio, targeting applications requiring small footprints and reliable timing performance in consumer or industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 48.461 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as rise/fall times and duty cycle. Cross-reference with other manufacturers offering similar surface-mount oscillators to ensure functional equivalence.
