What this LVDS transceiver does on the bench
The MAX9157EHJ+ is a half-duplex LVDS transceiver with four drivers and four receivers in a 32-TQFP package. It signals at 200 Mbps over a 3V to 3.6V supply, with 52 mV receiver hysteresis.
200 Mbps and 52 mV hysteresis — what those numbers mean for your bus
The 200 Mbps data rate is the maximum signaling speed across the LVDS pair. For a half-duplex link, that's the aggregate throughput for both transmit and receive.
