Procurement Notes

Verify the specific ordering suffix '-B' against the manufacturer's latest datasheet to confirm pinout and functional equivalence. Ensure that the 40-QFN (5x5) package dimensions align with your PCB footprint requirements. Cross-reference the CML output characteristics with your receiving circuit's input thresholds to guarantee proper signal level compatibility before finalizing procurement.

Selection Notes

Select this component when designing systems requiring bi-directional switching at speeds up to 10Gbps with minimal insertion loss. The integrated equalizer addresses channel loss issues without external components. Consider the 1.1 pF input capacitance for high-frequency signal integrity analysis. The CML output requires appropriate termination networks. Evaluate the 120mA supply current against your system's power budget constraints.
