18QHTF21-51.275-OE

Overview

The Mercury Electronics Ind. Co. Ltd part number 18QHTF21-51.275-OE is a standard crystal oscillator (XO) from the QuikXO series. It operates at a frequency of 51.275 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

LVCMOS output interface
Enable/Disable control function
QuikXO fast-delivery series

Applications

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

Procurement Notes

Verify the exact frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with your system design requirements. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to avoid assembly issues.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS compatibility. The enable/disable feature supports power-sensitive designs. Consider the small 2.0x1.6mm form factor for space-constrained applications requiring precise 51.275 MHz timing.

Part Context

This oscillator belongs to Mercury's QuikXO series, designed for rapid delivery of both standard and custom frequencies. Mercury Electronics Ind. Co. Ltd is a Taiwan-based manufacturer specializing in quartz crystals, oscillators, and filters, established as a pioneer in the local crystal industry since 1973.

Replacement Considerations

Check for direct substitutes within the same QuikXO family offering identical 51.275 MHz frequency and 1.8V LVCMOS specifications. Verify pinout and mechanical dimensions match the 4-SMD no-lead package to ensure compatibility without redesigning the PCB.
