MXL1543
Key Features
- The MXL1543 transceivers carry the high-speed clock and data signals while the MXL1544/MAX3175 carry the control signals
- The MXL1543 can be terminated by the MXL1344A software-selectable resistor termination network or by discrete termination networks
- A nocable mode is entered when all mode pins (M0, M1, and M2) are pulled high or left unconnected
- In nocable mode, supply current decreases to 0.5µA and all transmitter and receiver outputs are disabled (high impedance)
- Short-circuit current limiting and thermal shutdown circuitry protect the drivers against excessive power dissipation
