Procurement Notes

Verify the specific ordering suffix PQC to confirm the 24-pin QFN package configuration. Ensure that the power supply polarity matches the intended PCB layout design, as positive and negative supply configurations require different termination strategies. Confirm RoHS compliance status if required by local regulations before finalizing procurement orders.

Selection Notes

Select this component when a wide bandwidth phase shift is required for signals up to 17Gbps. Consider the thermal management requirements due to the 1.44W power dissipation, ensuring adequate heat sinking via the exposed pad. Evaluate the need for AC versus DC coupling based on the common mode voltage levels of the interfacing devices.
