Rev:A Date: 1/27/04 SP320 Complete +5V-Only V.35 Interface with RS-232 (V.28) Control Lines © Copyright 2004 Sipex Corporation 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 300 Ω over a ±2V range. Should the input of a driver be left open, an internal 400k Ω pullup resistor to V CC 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 5k Ω 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 3k Ω-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 charge pump still requires four external capacitors, but uses a four-phase voltage shifting technique to attain symmetrical ±10V power supplies. The capacitors can be as low as 0.1 µF with a 16 Volt rating. Polarized or non-polarized capacitors can be used. THEORY OF OPERATION The SP320 is a single chip +5V-only serial transceiver that supports all the signals neces- sary 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 50 Ω 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 ±15Ω, measured from short-circuited terminals.
