PCA9507 2-wire serial bus extender for HDMI DDC I2C-bus and SMBus Rev. 01 — 7 February 2008 Product data sheet 1. General description The PCA9507 is a 2-wire serial bus extender providing 3.3V to 5V level shift that allows up to 18meters bus extension for reliable DDC, I2C-bus or SMBus applications. While retaining all the operating modes and features of the I2C-bus system during the level shifts, it also permits extension of the I2C-bus by providing bidirectional buffering for both the data (SDA) and the clock (SCL) line as well as the rise time accelerator on portA enabling the bus to drive a load up to 1400pF or distance of 18m on portA, and 400pF onportB.UsingthePCA9507enablesthesystemdesignertoisolatebuscapacitanceto meet HDMI DDC version1.3 distance specification. The SDA and SCL pins are overvoltage tolerant and are high-impedance when the PCA9507 is unpowered. The portB drivers with static level offset behave much like the drivers on the PCA9515 device, while the portA drivers integrate the rise time accelerator, sink more current and eliminatethestaticoffsetvoltage.ThisresultsinaLOWonportBtranslatingintoanearly 0V LOW on portA. The static level offset design of the portB I/O drivers prevent them from being connected to another device that has rise time accelerator including the PCA9510, PCA9511, PCA9512, PCA9513, PCA9514, PCA9515, PCA9516A, PCA9517 (B-side), or PCA9518. The portA sides of two or more PCA9507s can be connected together, however, to allow a star topography with portA on the common bus, and portA canbeconnecteddirectlytoanyotherbufferwithstaticordynamicoffsetvoltage.Multiple PCA9507s can be connected in series, portA to portB, with no build-up in offset voltage with only time of flight delays to consider. Rise time accelerator on portA is turned on when input threshold is above 0.3V . CC(A) The PCA9507 drivers are not enabled unless V and V are above 2.7V. The EN CC(A) CC(B) pin can also be used to turn the drivers on and off under system control. Caution should be observed to only change the state of the enable pin when the bus is idle. The output pull-down on the portB internal buffer LOW is set for approximately 0.5V, while the input threshold of the internal buffer is set about 70mV lower (0.43V). When the portB I/O is driven LOW internally, the LOW is not recognized as a LOW by the input. This prevents a lock-up condition from occurring. 2.

Functional description Refer toFigure 1 “Functional diagram of PCA9507”. The PCA9507 consists of a pair of bidirectional open-drain I/Os specifically designed to support up-translation/down-translation between low voltages (as low as 2.7V) and a 3.3V or 5V I2C-bus and SMBus. The device contains a rise time accelerator on portA thatenablesthedevicetodrivealongcableoraheaviercapacitiveloadforDDC,I2C-bus andSMBusapplications.Withdualsupplyrails,thedevicetranslatesfromvoltageranges 2.7V to 5.5V down to a voltage as low as 2.7V without degradation of system performance. All I/Os are overvoltage tolerant to 5.5V even when the device is un-powered (V and/or V =0V). CC(B) CC(A) The PCA9507 includes a power-up circuit that keeps the output drivers turned off until V and V rise above 2.7V. V and V can be applied in any sequence at CC(A) CC(B) CC(A) CC(B) power-up.

PCA9507 NXP Semiconductors 2-wire serial bus extender for HDMI DDC I2C-bus and SMBus 6.3.2 Port B (SDAB and SCLB) SDAB and SCLB are standard I2C-bus with static level offset that has no rise time accelerator. The static level offset produces an output LOW of 0.5V (typical) at 6mA. As withthestandardI2C-bussystem,pull-upresistorsarerequiredtoprovidethelogicHIGH levels.Thesizeofthesepull-upresistorsdependsonthesystemrequirement,andshould meet the current sinking capability of the device that drives the buffer, as well as that of the buffer. The minimum and maximum pull-up resistors are determined and the pull-up resistor’s value is chosen to be within the minimum and maximum range. UsingEquation1, calculate the minimum pull-up resistor value: V –0.4 V RPU(min) = -----C---C----(-B--I--)-(--m----a--x---)-------------------- (1) OL(max) Where: R is the minimum pull-up resistor value for the open-drain SCLB and SDAB. PU(min) V is the maximum supply rail of the pull-up resistor. CC(B)(max) 0.4V is the maximum V of the device that drives the buffer on logic LOW. OL I at V =0.4V is the maximum sink current of the device that drives the buffer OL(max) OL on logic LOW. Themaximumpull-upresistorshouldalsobesizedsuchthattheRCtimeconstantmeets the standard I2C-bus rise time, which is 1m s for Standard-mode (100kHz) or 300ns for Fast-mode (400kHz). DDC bus complies with the I2C-bus Standard-mode and operates below 100kHz, and maximum rise time is 1m s using a simplified RC equation. UsingEquation2, calculate the maximum pull-up resistor value: R · C = 1.2· t (2) PU(max) L(max) r Where: R is the maximum allowable pull-up resistor on the SCLB and SDAB in order to PU(max) meet the I2C-bus rise time specification. C is the maximum allowable capacitance load (include the capacitance of driver, L(max) the line, and the buffer) in order to meet the rise time specification. t istherisetimespecifiedas1m s(forbusspeed100kHzorlower)and300ns(forbus r speed 400kHz or lower).

PCA9507 NXP Semiconductors 2-wire serial bus extender for HDMI DDC I2C-bus and SMBus According toFigure6, when portA of the PCA9507 is pulled LOW by a driver on the I2C-bus, a comparator detects the falling edge when it goes below 0.3V and causes CC(A) the internal driver on portB to turn on, causing portB to pull down to about 0.5V. When portB of the PCA9507 falls, first a CMOS hysteresis type input detects the falling edge andcausestheinternaldriveronportAtoturnonandpulltheportApindowntoground. In order to illustrate what would be seen in a typical application, refer toFigure11 and Figure12. If the bus master inFigure6 were to write to the slave through the PCA9507, waveforms shown inFigure11 would be observed on the Abus. This looks like a normal I2C-bus transmission except that the HIGH level may be as low as 2.7V, and the turn on and turn off of the acknowledge signals are slightly delayed. ThemasterdrivestheBbustogroundorletsitfloattoV asitsendsdatatotheslave CC(B) at the falling edge of the 8th clock, master releases SDAB on the Bbus and slave pulls SDAA on the Abus to ground, causing the PCA9507 to pull SDAB on the Bbus to 0.5V. At the falling edge of the 9th clock, the master again drives the Bbus and slave releases the Abus. Multiple PCA9507 portA sides can be connected in a star configuration (Figure9), allowing all nodes to communicate with each other.

The number of devices that can be connected in series is limited by repeater delay/time-of-flight considerations on the maximum bus speed requirements. PCA9507_1 © NXP B.V. 2008. All rights reserved.

Soldering of SMD packages Thistextprovidesaverybriefinsightintoacomplextechnology.Amorein-depthaccount of soldering ICs can be found in Application NoteAN10365 “Surface mount reflow soldering description”. 13.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to PrintedCircuitBoards(PCBs),toformelectricalcircuits.Thesolderedjointprovidesboth the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 13.2 Wave and reflow soldering Wavesolderingisajoiningtechnologyinwhichthejointsaremadebysoldercomingfrom a standing wave of liquid solder. The wave soldering process is suitable for the following: • Through-hole components • Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: • Board specifications, including the board finish, solder masks and vias • Package footprints, including solder thieves and orientation • The moisture sensitivity level of the packages • Package placement • Inspection and repair • Lead-free soldering versus SnPb soldering 13.3 Wave soldering Key characteristics in wave soldering are: • Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave • Solder bath specifications, including temperature and impurities PCA9507_1 © NXP B.V. 2008.

It is imperative that the peak temperatureishighenoughforthesoldertomakereliablesolderjoints(asolderpaste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table7 and8 Table 7.
