The 16-TSSOP package (0.173" body width) fits standard surface-mount assembly flows.
400 Mbps with full duplex — bus margin and channel count
At 400 Mbps, the LVDS output swing (typically 350 mV differential into a 100 Ω termination) keeps the eye open across backplane traces up to several meters, depending on cable quality and connector loss. The full-duplex architecture allows simultaneous transmit and receive on the same pair, halving the cable count compared to half-duplex alternatives. With two driver/receiver channels, this one device can serve two independent links or one link with redundant paths.
