I am planning to use LTC2864-1 in a circuit that 4 x RS-485 wiring are paralleled. Each RS-485 wiring has a termination resistor of 121Ohm, so the impedance in RS-485 will be 30Ohm approximately. Does this cause a problem such that LTC2864-1 cannot drive differential signaling? Do you have any similar example? If yes, do you have test results?
