18QHTF22-53.175-PD

Oscillators Overview

The 18QHTF22-53.175-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 53.175 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a Standby (Power Down) control function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.5mm x 2.0mm. This component is designed for applications requiring precise clock signals in space-constrained electronic systems.

Oscillators Feature Summary

• LVCMOS output interface for standard digital logic compatibility
• Integrated standby mode to reduce power consumption during idle periods
• Compact surface-mount package suitable for high-density PCB layouts

Oscillators Applications

• General clock signal generation in embedded systems
• Timing reference for digital communication interfaces
• Clock source for microcontrollers and FPGAs

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Ensure the 1.8V supply voltage aligns with your power architecture. Confirm that the 4-SMD no-lead package footprint matches your PCB silkscreen and solder mask definitions. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure reliability.

Oscillators Selection Notes

Select this oscillator when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. Consider the 2.5x2.0mm form factor if board space is limited. Evaluate the need for a power-down feature to manage system power budgets. Compare alternative frequencies within the same series if the exact 53.175 MHz is not strictly necessary, ensuring the selected part meets all timing specifications.

Oscillators Part Context

This component belongs to the H21/H22/H32/H53 SMD Oscillator series from Mercury Electronics. The manufacturer specializes in frequency control products including crystals, TCXOs, and oscillators. The 18QHTF22 prefix indicates a specific family of surface-mount oscillators designed for general-purpose clocking applications with standardized pinouts and electrical characteristics.

Oscillators Replacement Considerations

Consult the official Mercury Electronics datasheet for direct cross-references. Verify that any substitute part matches the 53.175 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Ensure equivalent electrical parameters such as phase noise and jitter are met for the specific application.
