DESCRIPTION…

The SP333 is a monolithic device that supports both Macintosh™ and PC serial interfaces.

RS-232 mode offers three (3) RS-232 drivers and five (5) RS-232 receivers. Mac mode

includes a differential driver and a single-ended inverting driver. Receivers in Mac mode

include one differential receiver, one non-inverting single-ended receiver and one inverting

single-ended receiver. An on-chip charge pump allows +5V-only operation, and a low power

THEORY OF OPERATION...

The single-ended AppleTalk driver also has

typical voltage output swings of ±5V under

loaded conditions, and ±8V under no-load con-

ditions. The single-ended AppleTalk driver can

maintain ±3.6V (minimum) swings under worst

case conditions of 450Ω to ground. The single-

ended AppleTalk driver can support data rates

over 400kbps.

The SP333 is a single chip device that can be

configured via software for either RS-232 or

AppleTalk™ interface modes at any time. The

SP333 is made up of three basic circuit ele-

ments: single-ended drivers and receivers, dif-

ferentialdriversandreceivers,andchargepump.

APPLETALK™ DRIVERS/RECEIVERS...

The receiver section of the SP333 is made up of

a differential receiver, a single-ended non-in-

verting receiver , and a single-ended inverting

receiver. The differential receiver has an input

sensitivity of ±200mV over a common mode

range of ±7V. The receivers have a typical input

resistance of 15kΩ (12kΩ minimum). The

differential receiver can receive data up to

10Mbps.

To program the SP333 for MacMode, Pin 25

should be connected to a logic HIGH. In

MacMode, the SP333 offers a complete

AppleTalk serial interface.

The driver section of the AppleTalk interface is

made up of a differential driver and a single-

ended inverting driver. The differential driver

has voltage swings that are typically ±5V on

each output pin under loaded conditions, and

typically ±8V under no-load conditions. The

differential driver can maintain ±3.6V (mini-

mum) swings (per pin) under worst case load

conditions of 450Ω between the differential

output.

The single-ended non-inverting receiver has a

±200mV input threshold, however, the input

voltage can vary between ±7V. The typical

input resistance of the single-ended non-invert-

ing receiver is 15kΩ (12kΩ minimum). The

single-ended non-inverting receiver can also

receive data up to 10Mbps.

The differential driver is equipped with a tri-

state control pin. When TXEN is a logic LOW,

thedifferentialdriverisactive. WhentheTXEN

pin is a logic HIGH, the differential driver

outputs are tri-stated. The TXEN pin only

functions in MacMode. The differential

AppleTalk driver can support data rates up to

10Mbps.

The SP333 also has a single-ended inverting

receiver input. This receiver is basically an RS-

232 receiver (R5 receiver) and is typically used

as a GPI (General Purpose Input) in the

AppleTalk interface. The GPI input has TTL-

compatible input thresholds that can receive

TGoddard/SP333/9617R0

SP333 RS-232/AppleTalk Programmable Transceiver

6

signals up to ±15V. The input resistance of the

single-ended inverting receiver is typically 5kΩ

(3kΩ to 7kΩ). The GPI receiver can operate up

to 10Mbps.

receivers features 500mV of hysteresis margin

to minimize the affects of noisy tranmission

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 resis-

tancewillmaintain3kΩ-7kΩovera±15Vrange.

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. Due to the on-chip ESD pro-

tection circuitry, the receiver inputs will be

clamped to ±15V levels; this should not affect

operation at ±30Volts. The RS-232 receivers

can operate over 400kbps.

SINGLEENDEDDRIVERS/RECEIVERS...

RS-232 (V.28) Drivers...

The single-ended drivers and receivers comply

the with the RS-232E and V.28 standards. The

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 driver

output voltage swing is ±9V with no load and is

guaranteed to be greater than ±5V under full

load. The drivers rely on the V+ and V- voltages

generated by the on-chip charge pump to main-

tain proper RS-232 output levels. With worst

case load conditions of 3kΩ and 2500pF, the

four RS-232 drivers can still maintain ±5V

output levels. The drivers can operate over

400kbps; the propagation delay from input to

output is typically 1.5µs. During shutdown, the

driver outputs will be put into a high impedance

tri-state mode.

CHARGE PUMP...

The charge pump is a Sipex-patented design

(5,306,954) and uses a unique approach com-

pared 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

capacitor values of the SP333 can be as low as

0.1µF. Figure 11a shows the waveform found

on the positive side of capacitor C2, and Figure

11b shows the negative side of capacitor C2.

There is a free-running oscillator that controls

the four phases of the voltage shifting. A de-

scription of each phase follows.

RS-232 (V.28) Receivers...

The RS-232 receivers convert RS-232 input

signals to inverted TTL signals. Each of the four

the Vdd storage capacitor. Simultaneously with

this, thepositivesideofcapacitorC1isswitched

to +5V and the negative side is connected to

ground, and the cycle begins again.

Phase 1

-Vss charge storage- During this phase of the

clock cycle, the positive side of capacitors C1

and C2 are initially charged to +5V. C1+ is then

switched to ground and charge in C1- is trans-

ferred to C2-. Since C2+ is connected to +5V,

the voltage potential across capacitor C2 is

now 10V.

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.

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.

The clock rate for the charge pump typically

operatesat15kHz.Theexternalcapacitorsshould

be 0.1µF with a 16V breakdown rating.

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 volt-

ages 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 is 3.5mA per driver. The external

power supplies should provide a power supply

sequence of either: +10V, –10V, and then +5V;

or –10V, +10V, and then +5V. It is critical that

the ±10V supplies are on before V_CC.

Phase 3

-Vdd charge storage- The third phase of the

clock is identical to the first phase- the trans-

ferredchargeinC1produces-5Vinthenegative

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.

Shutdown Mode

The SP333 can be put into a low power shut-

down mode by connecting the Shutdown pin

(SD, Pin 26) to a logic HIGH. During Shut-

down, the driver outputs are put into a high

impedance tri-state, and the charge pump is put

intostand-bymode. Thesupplycurrentdropsto

less than 10µA during shutdown and can be

activated in either RS-232 or AppleTalk mode.

For normal operation, the SD pin should be

connected to a logic LOW.

Receiver Enable

The SP333hasacontrollinetoenableordisable

the receiver outputs. Pin 3 (RXEN) is active

LOW; a logic LOW on Pin 3 will enable the

receiver outputs. A logic HIGH on Pin 3 will

disable the receiver outputs. The receiver en-

ablefunctioncanbeinitiatedineitherRS-232or

AppleTalk mode.

Wake-Up

The SP333 also features a "wake-up" function.

ThewakeupfunctionallowstheRS-232receiv-

ers to remain active during Shutdown mode

unless they are disabled by the Receiver Enable

control pin (Pin 3). The wake-up feature allows

users to take advantage of the low power Shut-

down mode and keep the receivers active to

accept an incoming "ring indicator" signal.
