8 DESCRIPTION The SP3EB/33EB transceivers meet the EIA/TIA-3 and V.8/V.4 communication protocols and can be implemented in batterypowered, portable, or hand-held applications such as notebook or palmtop computers. The SP3EB/33EB devices all feature Sipex's proprietary on-board charge pump circuitry that generates x V CC for RS-3 voltage levels from a single 3.0V to 5.5V power supply. This series is ideal for 3.3V-only systems, mixed 3.3V to 5.5V systems, or 5.0V-only systems that require true RS-3 performance. The SP3EB/33EB series have drivers that operate at a typical data rate of 50kbps fully loaded. The SP3EB and SP33EB are -driver/- receiver devices ideal for portable or hand-held applications. The SP3EB 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 SP3EB/33EB series are made up of three basic circuit blocks: 1. Drivers,. Receivers, and 3. the Sipex proprietary charge pump. Drivers The drivers are inverting level transmitters that convert TT or CMOS logic levels to ±5.0V EIA/TIA-3 levels inverted relative to the input logic levels. Typically, the RS-3 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-56 levels of ±3.7V with supply voltages as low as.7v. The drivers can guarantee a data rate of 50kbps fully loaded with 3KΩ in parallel with 1000pF, ensuring compatibility with PC-to-PC communication software. The slew rate of the driver output is internally limited to a maximum of 30V/µs in order to meet the EIA standards (EIA RS-3D.1.7, Paragraph 5). The transition of the loaded output from HIGH to OW also meets the monotonicity requirements of the standard. Figure 10 shows a loopback test circuit used to the RS-3 drivers. Figure 11 shows the test results of the loopback circuit with all drivers active at 10kbps with RS-3 loads in parallel with 1000pF capacitors. Figure 1 shows the test results where one driver was active at 50kbps and all drivers loaded with an RS-3 receiver in parallel with a 1000pF capacitor. A solid RS-3 data transmission rate of 50kbps provides compatibility with many designs in personal computer peripherals and AN applications. The SP3EB driver's output stages are turned off (tri-state) when the device is in shutdown mode. When the power is off, the SP3EB device permits the outputs to be driven up to ±1V. The driver's inputs do not have pull-up resistors. Designers should connect unused inputs to V CC or GND. In the shutdown mode, the supply current falls to less than 1µA, where SHDN = OW. When the SP3EB device is shut down, the device's driver outputs are disabled (tri-stated) and the charge pumps are turned off with V pulled down to V CC and V- pulled to GND. The time required to exit shutdown is typically 100µs. Connect SHDN to V CC if the shutdown mode is not used.

10 Receivers The receivers convert EIA/TIA-3 levels to TT or CMOS logic output levels. The SP3EB receivers have an inverting tri-state output. These receiver outputs (RxOUT) are tristated when the enable control EN = HIGH. In the shutdown mode, the receivers can be active or inactive. EN has no effect on TxOUT. The truth table logic of the SP3EB driver and receiver outputs can be found in Table. 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 Sipexpatented design (5,306,954) and uses a unique approach compared to older lessefficient designs. The charge pump still requires four external capacitors, but uses a fourphase 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 (V CC ) over the 3.0V to 5.5V range. In most circumstances, decoupling the power supply can be achieved adequately using a bypass capacitor at C5 (refer to Figures 8 and 9).

SP3EB Truth Table ogic for Shutdown and Enable Control In applications that are sensitive to power-supply noise, decouple V CC 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 V SS charge storage During this phase of the clock cycle, the positive side of capacitors C 1 and C are initially charged to V CC. C l is then switched to GND and the charge in C 1 is transferred to C. Since C is connected to V CC, the voltage potential across capacitor C is now times V CC. Phase V SS transfer Phase two of the clock connects the negative terminal of C to the V SS storage capacitor and the positive terminal of C 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 C 3, the positive side of capacitor C 1 is switched to V CC and the negative side is connected to GND. Phase 3 V DD charge storage The third phase of the clock is identical to the first phase the charge transferred in C 1 produces V CC in the negative terminal of C 1, which is applied to the negative side of capacitor C. Since C is at V CC, the voltage potential across C is times V CC. Phase 4 V DD transfer The fourth phase of the clock connects the negative terminal of C to GND, and transfers this positive generated voltage across C to C 4, the V DD storage capacitor.

11 This voltage is regulated to 5.5V. At this voltage, the internal oscillator is disabled. Simultaneous with the transfer of the voltage to C 4, the positive side of capacitor C 1 is switched to V CC 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 V CC ; in a noload 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 50kHz. The external capacitors can be as low as with a V breakdown voltage rating. ESD Tolerance The SP3EB/33EB series 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 electrostatic discharges and associated transients. The improved ESD tolerance is at least ±kv without damage nor latch-up. There are different methods of ESD testing applied: a) MI-STD-883, Method 30.7 b) IEC Air-Discharge c) IEC Direct Contact The Human Body Model has been the generally accepted ESD testing method for semiconductors. This method is also specified in MI-STD- 883, Method 30.7 for ESD testing. The premise of this ESD test is to simulate the human body s potential to store electrostatic energy and discharge it to an integrated circuit. The simulation is performed by using a test model as shown in Figure 18. 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. The IEC , formerly IEC801-, is generally used for testing ESD on equipment and systems. For system manufacturers, they must guarantee a certain amount of ESD protection since the system itself is exposed to the outside environment and human presence. The premise with IEC is that the system is required to withstand an amount of static electricity when ESD is applied to points and surfaces of the equipment that are accessible to personnel during normal usage. The transceiver IC receives most of the ESD current when the ESD source is applied to the connector pins. The test circuit for IEC is shown on Figure 19. There are two methods within IEC , the Air Discharge method and the Contact Discharge method. With the Air Discharge Method, an ESD voltage is applied to the equipment under test (EUT) through air. This simulates an electrically charged person ready to connect a cable onto the rear of the system only to find an unpleasant zap just before the person touches the back panel. The high energy potential on the person discharges through an arcing path to the rear panel of the system before he or she even touches the system. This energy, whether discharged directly or through air, is predominantly a function of the discharge current rather than the discharge voltage. Variables with an air discharge such as approach speed of the object carrying the ESD potential to the system and humidity will tend to change the discharge current. For example, the rise time of the discharge current varies with the approach speed. Date: 0/5/05 SP3EB/33EB True 3.0 to 5.5V RS-3 Transceivers Copyright 005 Sipex Corporation 11

13 R C R S SW1 SW DC Power Source C S Device Under Test Figure 18. ESD Test Circuit for Human Body Model The Contact Discharge Method applies the ESD current directly to the EUT. This method was devised to reduce the unpredictability of the ESD arc. The discharge current rise time is constant since the energy is directly transferred without the air-gap arc. In situations such as hand held systems, the ESD charge can be directly discharged to the equipment from a person already holding the equipment. The current is transferred on to the keypad or the serial port of the equipment directly and then travels through the PCB and finally to the IC. The circuit models in Figures 18 and 19 represent the typical ESD testing circuits used for all three methods. The C S is initially charged with the DC power supply when the first switch (SW1) is on. Now that the capacitor is charged, the second switch (SW) is on while SW1 switches off. The voltage stored in the capacitor is then applied through R S, the current limiting resistor, onto the device under test (DUT). In ESD tests, the SW switch is pulsed so that the device under test receives a duration of voltage.

14 For the Human Body Model, the current limiting resistor (R S ) and the source capacitor (C S ) are 1.5kΩ an 100pF, respectively. For IEC , the current limiting resistor (R S ) and the source capacitor (C S ) are 330Ω an 0pF, respectively. The higher C S value and lower R S value in the IEC model are more stringent than the Human Body Model. The larger storage capacitor injects a higher voltage to the test point when SW is switched on. The lower current limiting resistor increases the current charge onto the test point. I 30A A 0A t=0ns t t=30ns Figure 0.
