Oscillators Procurement Notes

Verify the specific suffix against official Mercury Electronics documentation to confirm functional differences between OE and PD variants. Ensure supply voltage requirements match the 1.8V specification. Confirm package dimensions align with PCB footprint constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS signaling standards. Consider the enable/disable feature if system-level power efficiency is a priority. Validate that the 3.796875 MHz frequency meets the target application's timing specifications without additional dividers.

Oscillators Part Context

This model belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The 'OE' suffix indicates a specific configuration variant, distinct from other suffixes like 'PD' which may imply different standby characteristics.
