18QHTF21-35.805-OE

Oscillators Overview

The 18QHTF21-35.805-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 35.805 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package.

Oscillators Feature Summary

• Supports active enable and disable control for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Designed as a standard XO (Crystal Oscillator) unit

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current documentation to ensure correct pinout and electrical specifications. Confirm that the 1.8V supply requirement aligns with the target system design before procurement. Ensure the 4-SMD no lead package dimensions fit the intended PCB layout constraints.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature makes it suitable for applications requiring dynamic power state control. Consider the 4-SMD form factor for space-constrained designs where surface mount assembly is preferred over through-hole options.

Oscillators Part Context

This part belongs to the Mercury Electronics series of quartz oscillators. The company has a history of manufacturing frequency control products since 1973. The 18QHTF21 series represents their SMD oscillator offerings, designed for reliability in various electronic applications requiring precise timing signals.

Oscillators Replacement Considerations

Check for parts with identical 35.805 MHz frequency, 1.8V supply, and LVCMOS output. Verify package compatibility for direct replacement. Cross-reference with other Mercury models in the H21 or similar series if available.
