• Utilizes LVCMOS output logic for digital interface compatibility
• Operates on a 1.8V supply voltage

Oscillators Applications

• Digital signal processing circuits
• 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 the required operating temperature range and load conditions match your design requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 38.5 MHz clock source with LVCMOS outputs is required. The 1.8V supply voltage makes it suitable for low-power digital systems. Confirm that the 4-SMD no-lead package dimensions fit within the available PCB space constraints.

Oscillators Part Context

This part belongs to the Mercury QHTF series of surface-mount crystal oscillators. The series typically offers standard frequencies with various voltage options. The 18 prefix indicates the 1.8V supply variant, while the 21 likely denotes the package type or series generation within the manufacturer's catalog.

Oscillators Replacement Considerations

Direct substitutes must match the 38.5 MHz frequency, LVCMOS output, and 1.8V supply voltage. Verify pinout compatibility for the 4-SMD no-lead package. Cross-reference with other Mercury models or industry-standard equivalents if lead times are critical.
