18QHTF21-21.630-OE

Oscillators Overview

The 18QHTF21-21.630-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 21.63 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features enable/disable control functionality. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes enable and disable control capability for power management
• Utilizes a small form factor SMD package suitable for space-constrained designs

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 21.63 MHz
• Embedded devices utilizing 1.8V logic levels

Oscillators Procurement Notes

Verify the specific suffix 'OE' corresponds to the required enable/disable functionality and output type when sourcing. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout requirements for proper soldering and mechanical stability.

Oscillators Selection Notes

Select this component when a precise 21.63 MHz timing source is needed within a low-voltage 1.8V environment. The choice depends on the requirement for active enable/disable control rather than continuous operation. Consider the physical size constraints imposed by the 2.0x1.6mm package against available board space.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in frequency control products. The series typically offers various frequencies and packages. This specific model represents a standard XO variant designed for modern portable and compact electronics applications requiring reliable clock signals.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical pinout and electrical characteristics but different frequencies or suffixes if functional differences are acceptable. Cross-reference with other manufacturers offering 21.63 MHz LVCMOS oscillators in 2.0x1.6mm packages.
