Date: 8/30/05 SP3220E/EB/EU High ESD RS-232 Driver/Receiver © Copyright 2005 Sipex Corporation Date: 8/22/05 SP3220E/EB/EU High ESD RS-232 Driver/Receiver © Copyright 2005 Sipex Corporation The SP3220E/EB/EU devices meet 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 SP3220E/EB/EU de- vices feature 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 SP3220EB device has a driver that can oper- ate at a data rate of 250Kbps fully loaded. The SP3220EU can operate at 1000Kbps; the SP3220E operates at a typical data rate of 235Kbps fully loaded. The SP3220E/EB/EU is a 1-driver/1-receiver de- vice ideal for portable or hand-held applications. The SP3220E/EB/EU features a 1µA shutdown mode that reduces power consumption and ex- tends battery life in portable systems. Its receivers remains active in shutdown mode, allowing exter- nal devices to be monitored using only 1µA supply current. THEORY OF OPERATION The SP3220E/EB/EU devices are made up of three basic circuit blocks: 1. Driver, 2. Receiver, and 3. the Sipex proprietary charge pump. Driver The driver is an inverting level transmitter that converts 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 degrada- tion in reliability. Driver outputs will meet EIA/TIA- 562 levels of +3.7V with supply voltages as low as 2.7V. The SP3220EB driver typically can operate at a data rate of 250Kbps fully loaded with 3K 1 in parallel with 1000pF, ensuring compatibility with PC-to-PC communication software. The SP3220EU driver can guarantee a data rate of 1000Kbps fully loaded with 3 1 in parallel with 250pF. The slew rate of the SP3220E and SP3220EB outputs are 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. The slew rate of the SP3220EU is not internally limited. This allows it to transmit at much faster data rates. 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 SP3220EB driver active at 250Kbps with an RS-232 load in parallel with a 1000pF capacitor. Figure 14 shows the test results where the SP3220EU driver was active at 1000Kbps and loaded with an RS-232 receiver in parallel with a 250pF capacitor. A solid RS-232 data transmission rate of 250Kbps provides com- patibility with many designs in personal computer peripherals and LAN applications. The SP3220E/EB/EU driver's output stage is turned off (high-Z) when the device is in shutdown mode. When the power is off, the SP3220E/EB/EU de- vice 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 SP3220E/EB/EU 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 100ms. 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 approxi- mately 3V.

Date: 8/30/05 SP3220E/EB/EU High ESD RS-232 Driver/Receiver © Copyright 2005 Sipex Corporation Date: 8/22/05 SP3220E/EB/EU High ESD RS-232 Driver/Receiver © Copyright 2005 Sipex Corporation 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 trans- fer of the voltage to C4, the positive side of capaci- tor 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. In a no–load condition V+ and V– will be symmetri- cal, since both V+ and V– are separately generated from VCC. 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. CHARGE PUMP DESIGN GUIDELINES The charge pump operates with 0.1 µF ca- pacitors for 3.3V operation. For other supply voltages, see the table for required capacitor values. Do not use values smaller than those listed. Increasing the capacitor values (e.g., by doubling in value) reduces ripple on the transmitter outputs and may slightly reduce power consumption. C2, C3, and C4 may be increased without changing C1’s value. The charge pump oscillator typically operates at greater than 250kHz allowing the pump to run efficiently with small 0.1 µF capacitors. Efficient operation depends on rapidly charg- ing and discharging C 1 and C 2, therefore capacitors should be mounted close to the IC and have low ESR (equivalent series resis- tance). Low cost surface mount ceramic capacitors (such as are widely used for power-supply decoupling) are ideal for use on the charge pump. However the charge pumps are de- signed to be able to function properly with a wide range of capacitor styles and values. If polarized capacitors are used the positive and negative terminals should be connected as shown in the Typical Operating Circuit. Voltage potential across any of the capacitors will never exceed 2 x VCC. Therefore capaci- tors with working voltages as low as 6.3V rating may be used with a 3.0V VCC supply. The reference terminal of the V+ capacitor may be connected either to VCC or ground, but if connected to ground a minimum 10V work- ing voltage is required. Higher working volt- ages and/or capacitance values may be ad- vised if operating at higher VCC or to provide greater stability as the capacitors age. Under lightly loaded conditions the intelligent pump oscillator maximizes efficiency by run- ning only as needed to maintain V+ and V-. Since interface transceivers often spend much of their time at idle, this power-efficient inno- vation can greatly reduce total power con- sumption. This improvement is made pos- sible by the independent phase sequence of the Sipex charge-pump design. dednemmocermuminiM eulavroticapacpmupegrahc tupnI ccVegatloV roticapaCpmupegrahC UE/BE/E0223PSrofeulav V6.3otV0.3 Fu1.0=4C–1C V5.5otV0.3 Fu22.0=4C–1C
