The receiver outputs can be switched to either or both drivers through the multiplexer control signals S0 and S1. This allows the flexibility to perform splitter or signal routing functions with a single device. The TIA/EIA-644 standard compliant electrical interface provides a minimum differential output voltage magnitude of 247 mV into a 100- Ω load and receipt of 100 mV signals with up to 1 V of ground potential difference between a transmitter and receiver. The SN65LVDM22 doubles the output drive current to achieve LVDS levels with a 50- Ω load.
