Oscillators Procurement Notes

Verify the specific ordering suffix against official datasheets to ensure correct output logic and voltage specifications. Confirm package dimensions and thermal requirements match the target PCB layout. Cross-reference the manufacturer's part number with distributor catalogs to avoid substitution errors during procurement.

Oscillators Selection Notes

Select this component when a 26.80156 MHz clock source is required with LVCMOS compatibility. Ensure the system design supports the 1.8V supply rail and accommodates the 4-SMD no-lead footprint. Evaluate the enable/disable pin requirements if power management strategies are part of the application design.

Oscillators Part Context

This model belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a small 2.0x1.6mm package. This specific variant provides a non-standard frequency optimized for certain communication or data transfer protocols requiring precise timing.

Oscillators Replacement Considerations

Direct replacements must match the 26.80156 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that any substitute component maintains identical enable/disable functionality and electrical characteristics to ensure circuit compatibility.
