18QHTF21-43.100-PD

Oscillators Overview

The 18QHTF21-43.100-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a nominal frequency of 43.1 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features a standby or power-down mode capability for energy management. It is housed in a compact 4-SMD, No Lead surface-mount package, designed for integration into electronic circuits requiring precise timing signals.

Oscillators Feature Summary

• Generates stable 43.1 MHz clock signals using LVCMOS logic levels
• Operates on a low 1.8V supply voltage for efficient power consumption
• Includes standby functionality to reduce power usage during idle periods
• Utilizes a small footprint 4-SMD no-lead package for space-constrained designs

Oscillators Applications

• General-purpose digital circuit timing references
• Embedded systems requiring low-voltage clock sources
• Portable electronics utilizing surface-mount assembly processes
• Communication modules needing standard frequency oscillators

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package dimensions fit within your PCB layout constraints. Check for any specific environmental temperature range requirements if operating outside standard commercial limits.

Oscillators Selection Notes

Select this component when a 43.1 MHz frequency is specifically required rather than a more common standard value. Consider the LVCMOS output compatibility with your downstream logic family. Evaluate the 1.8V operation against available power supplies in the target application. The standby feature should be utilized if power conservation is a priority during inactive phases of the device operation.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The manufacturer specializes in quartz crystals and various oscillator types including TCXO and VCTCXO. This specific model represents a basic fixed-frequency option within their portfolio, targeting applications that do not require temperature compensation but need reliable timing signals.

Oscillators Replacement Considerations

Direct substitutes must match the 43.1 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if critical. Cross-reference with other manufacturers offering similar surface-mount oscillators ensuring identical form factor and electrical specs.
