THEORY OF OPERATION The SP320 is a single chip +5V-only serial transceiver that supports all the signals necessary to implement a full V.35 interface. Three V.35 drivers and three V.35 receivers make up the clock and data signals. Four RS-232 (V.28) drivers and four RS-232 (V.28) receivers are used for control line signals for the interface. V.35 Drivers The V.35 drivers are +5V-only, low power voltage output transmitters. The drivers do not require any external resistor networks, and will meet the following requirements: 1. Source impedance in the range of 50Ω to 150Ω. 2. Resistance between short-circuited terminals and ground is 150Ω ±15Ω. 3. When terminated with a 100Ω resistive load the terminal to terminal voltage will be 0.55 Volts ±20% so that the A terminal is positive to the B terminal when binary 0 is transmitted, and the conditions are reversed to transmit binary 1. 4. The arithmetic mean of the voltage of the A terminal with respect to ground, and the B terminal with respect to ground will not exceed 0.6 Volts when terminated as in 3 above. The V.35 drivers can operate at data rates as high as 5Mbps. The driver outputs are protected against short-circuits between the A and B outputs and short circuits to ground. Two of the V.35 drivers, DRIN2 and DRIN3 are equipped with enable control lines. When the enable pins are high the driver outputs are disabled, the output impedance of a disabled driver will nominally be 300Ω. When the enable pins are low, the drivers are active. V.35 Receivers The V.35 receivers are +5V only, low power differential receivers which meet the following requirements: 1. Input impedance in the range of 100Ω ±10Ω. 2. Resistance to ground of 150 Ω ± 15 Ω , measured from short-circuited terminals.
Rev:B Mar 23-07
All of the V.35 receivers can operate at data rates as high as 5Mbps. The sensitivity of the V.35 receiver inputs is ±300mV. RS-232 (V.28) Drivers The RS-232 drivers are inverting transmitters, which accept either TTL or CMOS inputs and output the RS-232 signals with an inverted sense relative to the input logic levels. Typically, the RS-232 output voltage swing is ±9V with no load, and ±5V minimum with full load. The transmitter outputs are protected against infinite short-circuits to ground without degradation in reliability. In the power off state, the output impedance of the RS-232 drivers will be greater than 300Ω over a ±2V range. Should the input of a driver be left open, an internal 400kΩ pullup resistor to VCC forces the input high, thus committing the output to a low state. The slew rate of the transmitter output is internally limited to a maximum of 30V/µs in order to meet the EIA standards. The RS-232 drivers are rated for 120kbps data rates. RS-232 (V.28) Receivers The RS-232 receivers convert RS-232 input signals to inverted TTL signals. Each of the four receivers features 500mV of hysteresis margin to minimize the effects of noisy transmission lines. The inputs also have a 5kΩ resistor to ground; in an open circuit situation the input of the receiver will be forced low, committing the output to a logic high state. The input resistance will maintain 3kΩ-7kΩ over a ±15V range. The maximum operating voltage range for the receiver is ±30V, under these conditions the input current to the receiver must be limited to less than 100mA. The RS-232 receivers can operate to beyond 120kbps. 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 c harge pump still requires four external c apacitors, but uses a four-phase voltage shifting technique to attain symmetrical ±10V power supplies. The capacitors can be as low as 0.1µF with a 16 Volt rating. Polarized or non-polarized capacitors can be used.

+10V a) C2+ GND GND b) C2– –10V
Phase 4 -Vdd transfer- The fourth phase of the clock connects the negative terminal of C2 to ground and transfers the generated +10V across C2 to C4, the Vdd storage capacitor. Again, simultaneously with this, the positive side of capacitor C1 is switched to +5V and the negative side is connected to ground, and the cycle begins again. 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 15kHz. The external capacitors must be 0.1µF with a 16V breakdown rating. Shutdown Mode The SP320 can be put into a low power shutdown mode by bringing both TS000 (pin 3) and ENV35 (pin 9) low. In shutdown mode, the SP320 will draw less than 2mA of supply current. For normal operation, both pins should be connected to +5V. External Power Supplies For applications that do not require +5V only, external supplies can be applied at the V+ and V- pins. The value of the external supply voltages must be no greater than ±10V. The current drain from the ±10V supplies is used for the RS-232 drivers. For the RS-232 driver the current requirement will be 3.5mA per driver. It is critical the external power supplies provide a power supply sequence of : +10V, +5V, and then -10V. Applications Information The SP320 is a single chip device that can implement a complete V.35 interface. Three (3) V.35 drivers and three (3) V.35 receivers are used for clock and data signals and four (4) RS-232 (V.28) drivers and four (4) RS-232 (V.28) receivers can be used for the control signals of the interface. The following examples show the SP320 configured in either a DTE or DCE application.
Figure 1. Charge Pump Waveforms
Figure 1a shows the waveform found on the positive side of capacitor C2, and Figure 1b shows the negative side of capacitor C2. There is a free-running oscillator that 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 capactors C1 and C2 are initially charged to +5V. C1+ is then switched to ground and the charge in C1- is transferred to C2-. Since C2+ is connected to +5V, the voltage potential across capacitor C2 is now 10V. 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 ground, and transfers the generated -10V to C3. Simultaneously, the positive side of capacitor C1 is switched to +5V and the negative side is connected to ground. Phase 3 -Vdd charge storage- The third phase of the clock is identical to the first phase- the transferred charge in C1 produces -5V in the negative terminal of C1, which is applied to the negative side of capacitor C2. Since C2+ is at +5V, the voltage potential across C2 is +10V.
