XR32220EUER-L MaxLinear

XR32220 2-Driver/2-Receiver Intelligent RS-232 Transceiver with 1.65V to 5.5V Interface Description FEATURES The XR32220 product is a 2 driver/ 2 receiver RS-232 transceiver Meets true EIA/TIA-232-F Standards from featuring a variable low voltage logic interface, down to 1.65V. a +3.0V to 5.5V power supply Interoperable with EIA/TIA-232 and This product is intended for portable or hand-held applications such adheres to EIA/TIA-562 down to a +2.7V as notebook and palmtop computers. The XR32220EBER device power source feature slew-rate limited outputs for reduced crosstalk and EMI. 1.65V to 5.5V Logic Interface V pin L The XR32220EUER device is optimized for high speed with data AUTO ON-LINE circuitry automatically rates up to 1Mbps, easily meeting the demands of high speed RS-232 wakes up from a 1A shutdown applications. Regulated Charge Pump yields stable RS- 232 Outputs regardless of V variations The XR32220 uses an internal high-efficiency charge-pump power CC Enhanced ESD Specifications supply that requires only four 0.1F capacitors in 3.3V operation. This 15kV Human Body Model charge pump combined with MaxLinears driver architecture allow 15kV IEC61000-4-2 Air Discharge the XR32220 to deliver compliant RS-232 performance from a single 8kV IEC61000-4-2 Contact power supply ranging from +3.0V to +5.5V. Discharge 250Kbps min transmission rate The AUTO ON-LINE feature allows the device to automatically (speed grade B) wake-up during a shutdown state when an RS-232 cable is 1000Kbps min transmission connected and a connected peripheral is turned on. Otherwise, (speed grade U) the device automatically shuts itself down drawing less than 1A. -40C to 125C ambient operating temperature Typical Application Lead-free (RoHS 6) package V V L CC APPLICATIONS Industrial and Single Board Computers 0.1F 0.1F 18 19 Industrial and Process Control Equipment V V L CC Point-Of-Sales Equipment Building Security and Automation 21 C1+ 20 V+ 0.1 F 16 C1- 0.1F Charge 22 C2+ Pump 24 0.1 F V- 23 C2- 0.1F 10 T1IN T1OUT 5 TTL/CMOS RS-232 24 23 22 21 20 19 Inputs Outputs 9 6 T2IN T2OUT 1 18 NC VL VCC 2 17 NC GND 14 Shutdown 15 Auto On-line / R1IN 3 16 C1- OnLine XR32220 Control To -P Supervisor 13 Status Circuit 24 pin QFN 4 15 R2IN Online (4x4mm) 5 14 T1OUT Shutdown 12 3 R1OUT R1IN T2OUT 6 13 Status 5K TTL/CMOS RS-232 Outputs Inputs 7 8 9 10 11 12 11 4 R2OUT R2IN 5K GND 17 Figure 1.
