rev. 6/27/03 sp3222h/3232h 3.3v, 460 kbps rs-232 transceivers ? copyright 2003 sipex corporation 8 description the sp3222h and sp3232h are 2-driver/ 2-receiver devices ideal for portable or hand-held applications. the sp3222h features a 1 a shut- down 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 1 a supply current. the sp3222h/3232h transceivers meet the eia/ tia-232 and v.28/v.24 communication protocols. they feature sipex's proprietary on-board charge pump circuitry that generates 2 x v cc for rs-232 voltage levels from a single +3.0v to +5.5v power supply. the sp3222h/ 3232h drivers operate at a minimum data rate of 460kbps. theory of operation the sp3222h/3232h are 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 drivers have a minimum data rate of 460kbps fully loaded with 3k ? 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/ s 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 8 shows a loopback circuit used to test the rs-232 drivers. figure 9 shows the test results of the loopback circuit with all drivers active at 120kbps and rs-232 loads in parallel with 1000pf capacitors. figure 10 shows the test results where one driver is active at 460kbps and all drivers are loaded with an rs-232 receiver in parallel with a 1000pf capacitor. the sp3222h driver's output stages are tri-stated in shutdown mode. when the power is off, the sp3222h device permits the outputs to be driven up to +12v. because the driver's inputs do not have pull-up resistors, unused inputs should be connected to v cc or gnd. in the shutdown mode, the supply current is less than 1 a, where shdn = low. when the sp3222h 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 100 s. shdn is connected to v cc if the shutdown mode is not used. shdn has no effect on rxout or rxoutb. as they become active, the two driver outputs go to opposite rs-232 levels: one driver input is high and the other low. note that the drivers are enabled only when the magnitude of v- exceeds approximately 3v.

rev. 6/27/03 sp3222h/3232h 3.3v, 460 kbps rs-232 transceivers ? copyright 2003 sipex corporation 10 receivers the receivers convert eia/tia-232 levels to ttl or cmos logic output levels. the sp3222h receivers have an inverting tri-state output.receiver outputs (rxout) are tri-stated 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 sp3222h driver and receiver outputs can be found in table 2 . since receiver input is usually from a transmis- sion line where long cable lengths and system interference can degrade the signal and inject noise, the inputs have a typical hysteresis margin of 300mv. should an input be left unconnected, a 5k ? pulldown resistor to ground forces the output of the receiver high. charge pump the sipex patented charge pump (5,306,954) uses a four?hase voltage shifting technique to attain symmetrical 5.5v power supplies and requires four external capacitors. the internal power supply consists of a regulated dual charge pump that provides an output voltage of 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 0.1 f bypass capacitor at c5 (refer to figures 6 and 7 ). in applications that are sensitive to power-supply noise,v cc and ground can be decoupled with a capacitor of the same value as charge-pump capacitor c1. it is always important to physically locate bypass capacitors close to the ic. the charge pump operates in a discontinuous mode using an internal oscillator. if the output voltage is less than 5.5v, the charge pump is enabled. if the output voltage exceeds 5.5v, the charge pump is disabled. an oscillator controls the four phases of the voltage shifting. a description of each phase follows. phase 1: v ss charge storage (figure 12) during this phase of the clock cycle, the positive side of capacitors c 1 and c 2 are charged to v cc . c l + is then switched to gnd and the charge in c 1 is transferred to c 2 . since c 2 + is connected to v cc , the voltage potential across capacitor c 2 is now 2 times v cc . phase 2: v ss transfer (figure 13) phase two of the clock connects the negative terminal of c 2 to the v ss storage capacitor and the positive terminal of c 2 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 (figure 15) the third phase of the clock is identical to the first phase ?the charge transferred in c 1 produces ? cc in the negative terminal of c 1 , which is applied to the negative side of capacitor c 2 . since c 2 + is at v cc , the voltage potential across c 2 is 2 times v cc . table 2. truth table logic for shutdown and enable control n d h sn et u o x tt u o x r 00 e t a t s - i r te v i t c a 01 e t a t s - i r te t a t s - i r t 10 e v i t c ae v i t c a 11 e v i t c ae t a t s - i r t
rev. 6/27/03 sp3222h/3232h 3.3v, 460 kbps rs-232 transceivers ? copyright 2003 sipex corporation 11 phase 4: v dd transfer (figure 16) the fourth phase of the clock connects the negative terminal of c 2 to gnd, and transfers this positive generated voltage across c 2 to c 4 , the v dd 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 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 repeat. 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 no?oad 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 charge pump clock rate typically operates at 250khz. the external capacitors can be as low as 0.1 f with a 16v breakdown voltage rating. esd tolerance the sp3222h/3232h series incorporates ruggedized esd cells on all driver output and receiver input pins. the human body model has been the generally accepted esd testing method for semiconduc- tors. 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? 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 17 . this method will test the ic? capability to withstand an esd transient during normal handling such as in manufacturing areas where the ics tend to be handled frequently. for the human body model, the current limiting resistor (r s ) and the source capacitor (c s ) are 1.5k ? and 100pf, respectively. v cc = +5v ?v ?v +5v v ss storage capacitor v dd storage capacitor c 1 c 2 c 3 c 4 + + ++ figure 12. charge pump ?phase 1 figure 13. charge pump ?phase 2 v cc = +5v ?0v v ss storage capacitor v dd storage capacitor c 1 c 2 c 3 c 4 + + ++
