• Provides stable LVCMOS output signals
• Utilizes a leadless surface-mount package design

Oscillators Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm availability and exact specifications. Ensure compatibility with 1.8V supply requirements and LVCMOS interface standards before integration. Cross-reference the 4-SMD no-lead footprint dimensions with target PCB layout guidelines to prevent assembly errors during procurement.

Oscillators Selection Notes

Select this component when a 26.8625 MHz frequency is required with low-voltage operation. Consider the enable/disable feature if power efficiency is critical. Verify that the LVCMOS output level matches the receiving circuit's input thresholds. Confirm the physical package constraints fit within the designated area on the printed circuit board.

Oscillators Part Context

This model belongs to the Mercury Electronics XO series, focusing on standard frequency generation. The 18QHTF21 prefix indicates a specific form factor and performance tier within their oscillator lineup. It serves as a direct replacement for other oscillators requiring identical frequency and electrical characteristics in existing designs.

Oscillators Replacement Considerations

Direct substitutes must match the 26.8625 MHz frequency, 1.8V supply, and LVCMOS output. Verify pinout compatibility for the 4-SMD no-lead package. Check datasheets for equivalent parts from other manufacturers offering similar timing stability and operating temperature ranges.
