18QHTF21-49.152-OE

Overview

The 18QHTF21-49.152-OE is a quartz crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a nominal frequency of 49.152 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an Enable/Disable control function via the OE pin. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• LVCMOS output logic for standard digital interface compatibility
• Integrated enable/disable functionality for power management
• Compact surface-mount package design suitable for space-constrained applications

Applications

• High-performance digital signal processing systems
• Communication equipment requiring precise timing references
• Embedded systems utilizing LVCMOS-compatible clock inputs

Procurement Notes

Verify the specific suffix (OE) against official datasheets to confirm the presence of the enable pin functionality. Ensure the 1.8V supply requirement aligns with target circuit designs. Confirm package dimensions match PCB footprint specifications prior to procurement.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise 49.152 MHz timing. The LVCMOS output ensures compatibility with standard logic families. Consider the small form factor for dense board layouts where space is limited.

Part Context

This part belongs to the standard XO series from Mercury Electronics, focusing on quartz-based timing solutions. The manufacturer specializes in frequency control products including crystals, oscillators, and filters, established as a pioneer in Taiwan's crystal industry since 1973.

Replacement Considerations

Cross-reference with other 49.152 MHz LVCMOS oscillators in 4-SMD packages. Verify voltage and pinout compatibility before substitution.
