18QHTF21-6.300-OE

Overview

The 18QHTF21-6.300-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 6.3 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable pin functionality for power management
• Utilizes a leadless SMD package for surface-mount assembly

Applications

• General-purpose clock signal generation in embedded systems
• Timing reference sources for microcontrollers operating at 1.8V
• Consumer electronics requiring low-power oscillators

Procurement Notes

Verify the specific frequency suffix matches the required 6.3 MHz operation. Confirm the 1.8V supply voltage requirement aligns with the target circuit design. Ensure the 4-SMD No Lead package footprint corresponds to the PCB layout specifications. Check for any specific ordering suffixes that may indicate different packaging or temperature grades.

Selection Notes

Select this component when a precise 6.3 MHz timing source is required for 1.8V logic families. Consider the small 2.0x1.6mm footprint for space-constrained designs. Evaluate the need for active enable/disable control versus always-on operation. Compare against other Mercury Electronic series if higher frequencies or different voltages are needed.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic. The series offers various frequencies and voltage options within similar physical footprints. It is distinct from TCXO or VCTCXO models which offer temperature compensation. The 'OE' suffix typically denotes the enable feature present in this specific variant.

Replacement Considerations

Direct replacements must match the 6.3 MHz frequency, 1.8V supply, and LVCMOS output. Compatible alternatives include other 18QHTF21 variants with identical electrical parameters but different frequency suffixes. Cross-reference with other manufacturers offering 2.0x1.6mm XO packages with enable pins.
