SP320 Complete +5V-Only V.35 Interface with RS-232 (V.28) Control Lines

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 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.
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.
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
driver will nominally be 300Ω. When the enable
pins are low, the drivers are active.
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 0.1µF with a 16 Volt rating. 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.

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.
+10V
a) C2+
GND
GND
b) C2–
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.
–10V
Figure 1. Charge Pump Waveforms
The clock rate for the charge pump typically
operates at 15kHz. The external capacitors must
be 0.1µF with a 16V breakdown rating.
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.
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.
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.
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.
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.
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.
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.
