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
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.
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)
DuringthisphSSaseoftheclockcycle, 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: VSS Transfer (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: VDD Charge 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: VDD Transfer (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.
