18QHTF21-69.330-OE

Overview

The 18QHTF21-69.330-OE is a 69.33 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and utilizes LVCMOS output logic. The component features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This surface-mount device is designed for applications requiring precise timing signals within standard industrial temperature ranges.

Feature Summary

• Integrated enable/disable functionality for dynamic power control
• Compact 4-SMD no-lead surface mount package design
• LVCMOS output logic compatible with low-voltage digital systems

Applications

• General clock signal generation for embedded systems
• Timing reference for consumer electronics devices
• Industrial control modules requiring stable frequency sources

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage levels and output types. Confirm that the 1.8V supply requirement aligns with the target system's power rails. Check for any environmental certifications or RoHS compliance status if mandated by project specifications. Ensure the 2.0x1.6 mm footprint matches the PCB layout constraints.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 69.33 MHz frequency. Consider the Enable/Disable feature if power efficiency during idle states is critical. Evaluate the small form factor against available board space. Compare performance against other Mercury oscillators if different voltage options or frequencies are needed.

Part Context

This part belongs to the QHTF series of quartz crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The '18' prefix indicates the 1.8V supply variant, while '69.330' specifies the nominal frequency. The '-OE' suffix denotes the specific output enable configuration and packaging type.

Replacement Considerations

Direct substitutes may include other 69.33 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters before swapping. Alternative Mercury models with different voltage ratings require circuit modification.
