Ideal for high-speed RS-232 applications
The MxL83947 device is a 3 driver/5 receiver RS-232 transceiver intended for portable or hand-held applications such as notebook and industrial computers. The MxL83947 includes one complementary receiver that remains alert to monitor an external device’s Ring Indicate signal while the device is shut down. The device is optimized for high speed with data rates up to 1Mbps, and low propagation delays and channel to channel skew, easily meeting the demands of high-performance RS-232 applications. The MxL83947 uses an internal high-efficiency charge-pump power supply that requires only 0.1µF capacitors for operation. This charge pump and MaxLinear’s driver architecture allow the device to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The AUTO-ONLINE® feature allows the device to automatically wake up during a shutdown state when an RS-232 cable is connected and a connected peripheral is turned on. Otherwise, the device automatically shuts itself down, drawing less than 0.8µA.
