18QHTF21-4.9152-PD

Oscillators Overview

The 18QHTF21-4.9152-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 4.9152 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• LVCMOS output logic interface
• Integrated standby power-down capability
• Compact surface-mount form factor

Oscillators Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-profile, 1.8V LVCMOS oscillator is required for space-constrained designs. Consider the 4.9152 MHz frequency suitability for your specific data rate or clock division needs. Evaluate the standby feature if power management is critical. Compare package dimensions against available board real estate to ensure fitment within the designated area.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and oscillators. The manufacturer has decades of experience in frequency control products. This specific model represents a standard XO variant designed for general-purpose timing applications requiring small size and low voltage operation.

Oscillators Replacement Considerations

Check for direct substitutes with identical 4.9152 MHz frequency, 1.8V supply, and LVCMOS output. Verify pin compatibility and package dimensions (2.0x1.6mm SMD). Ensure thermal and electrical characteristics match the original specification to maintain system performance without redesign.
