SN65HVD485E SLLS612E–JUNE2004–REVISEDDECEMBER2015 www.ti.com 9 Detailed Description 9.1 Overview The SN65HVD485E device is a half-duplex RS-485 transceiver suitable for data transmission at rates up to 10 Mbps over controlled-impedance transmission media (such as twisted-pair cabling). Up to 64 units of the SN65HVD485E device can share a common RS-485 bus due to the low bus-input currents of the device.

It features a typical hysteresis of 30 mV to improve noise immunity. Internal ESD protection circuits protect the transceiver bus terminals against ±15-kV Human Body Model (HBM) electrostatic discharges. 9.4 Device Functional Modes When the driver enable pin (DE) is logic high, the differential outputs A and B follow the logic states at data input D. A logic high at D causes A to turn high and B to turn low. In this case, the differential output voltage defined as V = V – V is positive. When D is low, the output states reverse, B turns high, A is low, and V is OD A B OD negative. WhenDEislow,bothoutputsturnhighimpedance.Inthiscondition,thelogicstateatDisirrelevant.TheDEpin has an internal pulldown resistor to ground; thus when left open, the driver is disabled (high impedance) by default.

Half-DuplexTransceiverConfigurations Usingindependentenablelinesprovidesthemostflexiblecontrolasitallowsforthedriverandthereceivertobe turned on and off individually. While this configuration requires two control lines, it allows for selective listening intothebustrafficwhetherthedriveristransmittingdataornot. Combining the enable signals simplifies the interface to the controller by forming a single direction-control signal. In this configuration, the transceiver operates as a driver when the direction-control line is high and as a receiver whenthedirection-controllineislow. Additionally, only one line is required when connecting the receiver-enable input to ground and controlling only the driver-enable input. In this configuration, a node receives the data from the bus, receives the data it sends, andcanverifythatthecorrectdatahasbeentransmitted. 10.2 Typical Application An RS-485 bus consists of multiple transceivers connecting in parallel to a bus cable. To eliminate line reflections, each cable end is terminated with a termination resistor (R ) whose value matches the characteristic T impedance (Z ) of the cable. This method, known as parallel termination, allows for higher data rates over longer 0 cablelength. R R R R A A RE RE B RT RT B DE DE D D D D A B A B R R D D R RE DE D R RE DE D Figure18.

While most RS-485 systems use data rates between 10 kbps and 100 kbps, some applications require data rates up to 250 kbps at distances of 4000 feet and longer. Longer distances are possible by allowing for small signal jitter of upto5or10%. 10000 5%, 10%, and 20% Jitter h (ft) 1000 gt Conservative n e Characteristics L e bl 100 a C 10 100 1k 10k 100k 1M 10M 100M Data Rate(bps) Figure19. CableLengthvsDataRateCharacteristic 10.2.1.2 StubLength When connecting a node to the bus, the distance between the transceiver inputs and the cable trunk, known as the stub, must be as short as possible. Stubs present a nonterminated piece of bus line that can introduce reflections as the length of the stub increases. As a general guideline, the electrical length, or round-trip delay, of a stub must be less than one-tenth of the rise time of the driver; thus giving a maximum physical stub length as showninEquation1.

SN65HVD485E SLLS612E–JUNE2004–REVISEDDECEMBER2015 www.ti.com Typical Application (continued) Receiver failsafe is accomplished by offsetting the receiver thresholds such that the input indeterminate range does not include zero volts differential. To comply with the RS-422 and RS-485 standards, the receiver output must output a high when the differential input V is more positive than 200 mV, and it must output a Low when ID V is more negative than –200 mV. The receiver parameters that determine the failsafe performance are V , ID IT+ V , and V (the separation between V and V ). As shown in the Electrical Characteristics: Receiver table, IT– hys IT+ IT– differential signals more negative than –200 mV cause a low receiver output, and differential signals more positivethan200mVcauseahighreceiveroutput. When the differential input signal is close to zero, it is still above the V threshold, and the receiver output is IT+ High. Only when the differential input is more than V below V does the receiver output transition to a Low hys IT+ state. Therefore, the noise immunity of the receiver inputs during bus fault conditions includes the receiver hysteresisvalue(V )aswellasthevalueofV . hys IT+ 10.2.2 DetailedDesignProcedure To protect bus nodes against high-energy transients, the implementation of external transient protection devices isnecessary. 5V 110000 nnFF 110000n nFF 101 k0Ωk VCC R1 R RxD MCU/ RE A TVS UART DE B DIR D TxD R2 101 k0Ωk GND Figure20.

Power supply current is delivered to the bus load and to the transceiver circuitry. For a typical RS-485 bus configuration, the load that an active driver must drive consists ofallofthereceivingnodesplustheterminationresistorsateachendofthebus. The load presented by the receiving nodes depends on the input impedance of the receiver. The TIA/EIA-485-A standarddefinesaunitloadasallowingupto1mA.Withupto32unitloadsallowedonthebus,thetotalcurrent supplied to all receivers can be as high as 32 mA.

SN65HVD485E www.ti.com SLLS612E–JUNE2004–REVISEDDECEMBER2015 The current in the termination resistors depends on the differential bus voltage. The standard requires active drivers to produce at least 1.5 V of differential signal. For a bus terminated with one standard 120-Ω resistor at each end, this sums to 25-mA differential output current whenever the bus is active. Typically, the SN65HVD485E device can drive more than 25 mA to a 60-Ω load, which results in a differential output voltage higherthantheminimumrequiredbythestandard(seeFigure2). Supply current increases with signaling rate primarily because of the totem pole outputs of the driver. When these outputs change state, there is a moment when both the high-side and low-side output transistors are conducting, which creates a short spike in the supply current. As the frequency of state changes increases, more powerisused. 10.2.3 ApplicationCurve Figure21.SN65HVD485ESingle-EndedInput(Top),DifferentialOutput(Middle),andSingle-EndedOutput (Bottom)at10MHz Copyright©2004–2015,TexasInstrumentsIncorporated SubmitDocumentationFeedback 17 ProductFolderLinks:SN65HVD485E

SN65HVD485E SLLS612E–JUNE2004–REVISEDDECEMBER2015 www.ti.com 11 Power Supply Recommendations To ensure reliable operation at all data rates and supply voltages, each supply must be decoupled with a 100-nF ceramic capacitor located as close as possible to the supply pins. This helps to reduce supply voltage ripple present on the outputs of switched-mode power supplies and also helps to compensate for the resistance and inductanceofthePCBpowerplanes. 12 Layout 12.1 Layout Guidelines Robust and reliable bus-node design often requires the use of external transient-protection devices to protect against EFT and surge transients that may occur in industrial environments. Because these transients have a wide frequency bandwidth (from approximately 3 MHz to 3 GHz), high-frequency layout techniques must be appliedduringPCBdesign. 1. Placetheprotectioncircuitryclosetothebusconnectortopreventnoisetransientsfromenteringtheboard. 2. Use V and ground planes to provide low-inductance power distribution. High-frequency currents tend to CC followthepathofleastinductanceandnotthepathofleastresistance. 3. Design the protection components into the direction of the signal path. Do not force the transient currents to divertfromthesignalpathtoreachtheprotectiondevice. 4. Apply 100-nF to 220-nF bypass capacitors as close as possible to the V pins of transceiver, UART, or CC controllerICsontheboard. 5. Use at least two vias for V and ground connections of bypass capacitors and protection devices to CC minimizeeffectiveviainductance. 6. Use 1-kΩ to 10-kΩ pullup or pulldown resistors for enable lines to limit noise currents in these lines during transientevents. 7. Insert series pulse-proof resistors into the A and B bus lines if the TVS clamping voltage is higher than the specified maximum voltage of the transceiver bus terminals. These resistors limit the residual clamping currentintothetransceiverandpreventitfromlatchingup. 8. While pure TVS protection is sufficient for surge transients up to 1 kV, higher transients require metal-oxide varistors (MOVs), which reduces the transients to a few hundred volts of clamping voltage and transient blockingunits(TBUs)thatlimittransientcurrenttolessthan1mA. 12.2 Layout Example 5 Viatoground R C 4 ViatoVCC 6 R 1 R MCU P 7 R M R 5 J TVS 6 R SN65HVD485E 5 Figure22.
