Oscillators Procurement Notes

Verify the specific ordering suffix PD against the manufacturer's official datasheet to confirm the exact pinout and electrical characteristics. Ensure that the 1.8V supply requirement aligns with the target circuit design. Confirm the 4-SMD package dimensions match the PCB footprint requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 17.142838 MHz reference is required in space-constrained designs. The choice depends on the necessity for LVCMOS outputs and the availability of a 1.8V power rail. Consider the power-down feature if system-level power management is a priority. Validate thermal and mechanical constraints associated with the small form factor.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products.
