SP3220B/U Typical Operating Circuits Rev. 7/8/03 SP3220B/U +3.0 to +5.0V RS-232 Transceivers © Copyright 2003 Sipex Corporation 8 DESCRIPTION The SP3220B/U device meets the EIA/TIA-232 and V.28/V.24 communication protocols and can be implemented in battery-powered, portable, or hand-held applications such as notebook or palmtop computers. The SP3220B/ U device features Sipex's proprietary on-board charge pump circuitry that generates 2 x VCC for RS-232 voltage levels from a single +3.0V to +5.5V power supply. This series is ideal for +3.3V-only systems, mixed +3.0V to +5.5V systems, or +5.0V-only systems that require true RS-232 performance. The SP3220B device has a driver that can operate at a data rate of 250Kbps fully loaded. The SP3220U can Operate at 1000Kbps The SP3220B/U is a 1-driver/1-receiver device ideal for portable or hand-held applications. The SP3220B/U features a 1µA shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1µA supply current. THEORY OF OPERATION The SP3220B/U device is made up of three basic circuit blocks: 1. Drivers, 2. Receivers, and 3. the Sipex proprietary charge pump. Drivers The drivers are inverting level transmitters that convert TTL or CMOS logic levels to +5.0V EIA/TIA-232 levels inverted relative to the input logic levels. Typically, the RS-232 output voltage swing is +5.5V with no load and at least +5V minimum fully loaded. The driver outputs are protected against infinite short-circuits to ground without degradation in reliability. Driver outputs will meet EIA/TIA-562 levels of +3.7V with supply voltages as low as 2.7V. The SP3220B drivers typically can operate at a data rate of 250Kbps fully loaded with 3KΩ in parallel with 1000pF, ensuring compatibility with PC-to-PC communication software. Rev. 7/8/03 SP3220B/U +3.0 to +5.0V RS-232 Transceivers © Copyright 2003 Sipex Corporation The SP3220U drivers can guarantee a data rate of 1000Kbps fully loaded with 3Ω in parallel with 250pF. The slew rate of the SP3220B output is internally limited to a maximum of 30V/µs in order to meet the EIA standards (EIA RS-232D 2.1.7, Paragraph 5). The transition of the loaded output from HIGH to LOW also meets the monotonicity requirements of the standard. Figure 12 shows a loopback circuit used to test the RS-232 driver. Figure 13 shows the test results of the loopback circuit with the SP3220B driver active at 250Kbps with an RS-232 load in parallel with a 1000pF capacitor. Figure 14 shows the test results where the SP3220U driver was active at 1000Kbps and loaded with an RS232 receiver in parallel with a 250pF capacitor. A solid RS-232 data transmission rate of 250Kbps provides compatibility with many designs in personal computer peripherals and LAN applications. The SP3220B/U driver's output stage is turned off (high-Z) when the device is in shutdown mode. When the power is off, the SP3220B/U device permits the outputs to be driven up to +12V. The driver's input does not have pull-up resistors. Designers should connect an unused input to VCC or GND. In the shutdown mode, the supply current falls to less than 1µA, where SHDN = LOW. When the SP3220B/U device is shut down, the device's driver output is disabled (high-Z) and the charge pump is turned off with V+ pulled down to VCC and V- pulled to GND. The time required to exit shutdown is typically 100µs. Connect SHDN to VCC if the shutdown mode is not used. SHDN has no effect on RxOUT. Note that the driver is enabled only when the magnitude of V- exceeds approximately 3V. 9 VCC + C5 0.1µF C1+ 0.1µF C1C2+ 0.1µF C2- VCC V+ C3 + 0.1µF C1 + SP3220B/U C2 + VC4 + 0.1µF LOGIC INPUTS LOGIC OUTPUTS TxIN TxOUT RxOUT 5kΩ EN GND RxIN *SHDN VCC (SP3220B 1000pF) (SP3220U 250pF) Figure 12.

SP3220U Driver Loopback Test Results at 1Mbps Rev. 7/8/03 SP3220B/U +3.0 to +5.0V RS-232 Transceivers © Copyright 2003 Sipex Corporation 10 Receivers The receiver converts EIA/TIA-232 levels to TTL or CMOS logic output levels. The receiver has an inverting high-impedance output. This receiver output (RxOUT) is at high-impedance when the enable control EN = HIGH. In the shutdown mode, the receiver can be active or inactive. EN has no effect on TxOUT. The truth table logic of the SP3220B/U driver and receiver outputs can be found in Table 2. Since receiver input is usually from a transmission line where long cable lengths and system interference can degrade the signal, the inputs have a typical hysteresis margin of 300mV. This ensures that the receiver is virtually immune to noisy transmission lines. Should an input be left unconnected, a 5kΩ pulldown resistor to ground will commit the output of the receiver to a HIGH state. Charge Pump The charge pump is a Sipex–patented design (U.S. 5,306,954) and uses a unique approach compared to older less–efficient designs. The charge pump still requires four external capacitors, but uses a four–phase voltage shifting technique to attain symmetrical 5.5V power supplies. The internal power supply consists of a regulated dual charge pump that provides output voltages 5.5V regardless of the input voltage (VCC) over the +3.0V to +5.5V range. In most circumstances, decoupling the power supply can be achieved adequately using a 0.1µF bypass capacitor at C5 (refer to Figures 11). In applications that are sensitive to powersupply noise, decouple VCC to ground with a capacitor of the same value as charge-pump capacitor C1. Physically connect bypass capacitors as close to the IC as possible. The charge pumps operate in a discontinuous mode using an internal oscillator. If the output voltages are less than a magnitude of 5.5V, the charge pumps are enabled. If the output voltage exceed a magnitude of 5.5V, the charge pumps are disabled. This oscillator controls the four phases of the voltage shifting. A description of each phase follows. Phase 1 — VSS charge storage — During this phase of the clock cycle, the positive side of capacitors C1 and C2 are initially charged to VCC. Cl+ is then switched to GND and the charge in C1– is transferred to C2–. Since C2+ is connected to VCC, the voltage potential across capacitor C2 is now 2 times VCC. Phase 2 — VSS transfer — Phase two of the clock connects the negative terminal of C2 to the VSS storage capacitor and the positive terminal of C2 to GND. This transfers a negative generated voltage to C 3. This generated voltage is regulated to a minimum voltage of -5.5V. Simultaneous with the transfer of the voltage to C3, the positive side of capacitor C1 is switched to VCC and the negative side is connected to GND. Phase 3 — VDD charge storage — The third phase of the clock is identical to the first phase — the charge transferred in C1 produces –VCC in the negative terminal of C1, which is applied to the negative side of capacitor C2. Since C2+ is at VCC, the voltage potential across C2 is 2 times VCC. SHDN 0 0 1 1 EN 0 1 0 1 TxOUT Tri-state Tri-state Active Active RxOUT Active Tri-state Active Tri-state Table 2. Truth Table Logic for Shutdown and Enable Control Rev. 7/8/03 SP3220B/U +3.0 to +5.0V RS-232 Transceivers © Copyright 2003 Sipex Corporation 11 Phase 4 — VDD transfer — The fourth phase of the clock connects the negative terminal of C2 to GND, and transfers this positive generated voltage across C2 to C4, the VDD storage capacitor. This voltage is regulated to +5.5V. At this voltage, the internal oscillator is disabled. Simultaneous with the transfer of the voltage to C4, the positive side of capacitor C1 is switched to VCC and the negative side is connected to GND, allowing the charge pump cycle to begin again. The charge pump cycle will continue as long as the operational conditions for the internal oscillator are present. Since both V+ and V– are separately generated from VCC; in a no–load condition V+ and V– will be symmetrical. Older charge pump approaches that generate V– from V+ will show a decrease in the magnitude of V– compared to V+ due to the inherent inefficiencies in the design. The clock rate for the charge pump typically operates at 250kHz. The external capacitors can be as low as 0.1µF with a 16V breakdown voltage rating. ESD Tolerance The SP3220B/U device incorporates ruggedized ESD cells on all driver output and receiver input pins. The ESD structure is improved over our previous family for more rugged applications and environments sensitive to electro-static discharges and associated transients. The Human Body Model has been the generally accepted ESD testing method for semiconductors. This method is also specified in MIL-STD-883, Method 3015.7 for ESD testing. The premise of this ESD test is to simulate the human body’s potential to store electro-static energy and discharge it to an integrated circuit. The simulation is performed by using a test model as shown in Figure 20. This method will test the IC’s capability to withstand an ESD transient during normal handling such as in manufacturing areas where the ICs tend to be handled frequently.
