Description
The XR32220 product is a 2 driver/ 2 receiver RS-232 transceiver featuring a variable low voltage logic interface, down to 1.65V. This product is intended for portable or hand-held applications such as notebook and palmtop computers. The XR32220EBER device feature slew-rate limited outputs for reduced crosstalk and EMI. The XR32220EUER device is optimized for high speed with data rates up to 1Mbps, easily meeting the demands of high speed RS-232 applications.
The XR32220 uses an internal high-efficiency charge-pump power supply that requires only four 0.1μF capacitors in 3.3V operation. This charge pump combined with MaxLinear’s driver architecture allow the XR32220 to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V.
The AUTO ON-LINE® feature allows the device to automatically “wake-up” during a shutdown state when an RS-232 cable is c...
