SN65LVDS180PWR is a full-duplex LVDS transceiver in a 14-TSSOP package.
The 150 Mbps data rate is the maximum serial bit rate the driver can sustain under specified load conditions. For a full-duplex link, that means simultaneous transmit and receive at the same rate — no half-duplex turnaround overhead. In practice, budget for cable length and connector quality: at 150 Mbps over a few meters of twisted pair, you get clean eye diagrams; pushing to longer runs or higher noise environments may need a slower rate or better cable.
