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.

THEORY OF OPERATION

The SP319 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.

RS-232 (V.28) Drivers

The RS-232 drivers are inverting transmitters,

which accept either TTL or CMOS inputs and

outputtheRS-232signalswithaninvertedsense

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

transmitteroutputsareprotectedagainstinfinite

short-circuits to ground without degradation in

reliability.

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:

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

V_CCforces 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.

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.

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.

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

driverwillnominallybe300Ω. Whentheenable

pins are low, the drivers are active.

CHARGE PUMP

The charge pump is a Sipex patented design

(U.S. 5,306,954) that uses an innovative

approach. The charge pump, with four external

capacitors, uses a four-phase voltage shifting

technique to attain a symmetrical +10V power

supply. The capacitors can be as low as

0.1µF with a 16 Volt rating. Either polarized

or non-polarized capacitors can be used.

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 150Ω +15Ω,

measured from short-circuited terminals.

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 design.

Shutdown Mode

–10V

The SP319 can be put into a low power

shutdown mode by bringing both TS000 (pin 3)

and ENV35 (pin 9) low. In shutdown mode,

SP319 draws less than 2mA. For normal

operation, both pins should be connected to +5V.

Figure 20. Charge Pump Waveforms

Figure 20 shows the waveforms on the positive

and negative sides of capacitor C2 respectively.

A free-running oscillator controls the four

phases of the voltage shifting. A description

of each phase follows.

Termination Enable

The SP319 includes a termination enable pin

that connects or disconnects the receiver input

termination circuitry. A TTL logic LOW atENT

(pin 75) will connect the "Y" termination network

to the V.35 receiver inputs. A TTL logic HIGH

at ENT (pin 75) will disconnect the "Y" termi-

nation network and the receivers will operate as

V.11 compliant receivers. The ENT pin has an

internal pull-down resistor so that a floating

input will enable the termination network. The

SP319 is compatible with the SP320 since pin

75 on the SP320 is designated as a no connect.

Phase 1: V Charge Storage (Figure 21)

Duringthisph^SSaseoftheclockcycle, thepositive

side of capacitors C1 and C2 are charged to

+5V. C1+ is switched to ground and the charge

on C1- is transferred to C2-. Since C2+ is

connected to +5V, the voltage potential across

capacitor C2 becomes 10V.

Phase 2: V_SSTransfer (Figure 22)

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.

External Power Supplies

For applications where separate external

supplies can be applied at the V+ and V- pins.

Thevalueoftheexternalsupplyvoltagesshould

notexceed+10V. Itiscriticaltheexternalpower

supplies provide a power supply sequence of :

+10V, +5V, and then -10V.

Phase 3: V_DDCharge Storage (Figure 23)

The third phase of the clock is identical to

the first phase - the transferred charge on C1

produces -5V on 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.

Applications Information

The SP319 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. Figures 25 and 28

show the SP319 configured in DTE and DCE

applications along with an ISO-2593 pin out.

Phase 4: V_DDTransfer (Figure 24)

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. The positive side of capacitor

C1 is switched to +5V and the negative side is

connected to ground, and the cycle begins again.
