Serializers, Deserializers Procurement Notes

Verify the specific suffix (SQX vs SQE) against the design file to ensure package compatibility, as both denote WQFN variants but may differ in reel specifications or moisture sensitivity handling requirements during assembly. Confirm RoHS compliance status with the current datasheet revision before finalizing procurement orders.

Serializers, Deserializers Selection Notes

Select this component when designing systems that require consolidating multiple parallel digital signals into a single differential pair. Ensure the receiving deserializer matches the 1.05 Gbps speed grade and utilizes compatible CML signaling. Validate that the PCB layout can accommodate the 40-pin WQFN footprint and thermal requirements for the specified operating temperature range.
