N3 2 QF HV IP4786CZ32 DVI and HDMI interface ESD and overcurrent protection, DDC/CEC buffering, hot plug detect and backdrive protection Rev. 1 — 15 April 2011 Product data sheet 1. General description The IP4786CZ32 is designed to protect High-Definition Multimedia Interface (HDMI) transmitter host interfaces. It includes HDMI 5 V overcurrent / overvoltage protection, Data Display Channel (DDC) buffering and decoupling, hot plug detect, backdrive protection, Consumer Electronic Control (CEC) buffering and decoupling, and ±8 kV contact ElectroStatic Discharge (ESD) protection for all I/Os in accordance with the IEC 61000-4-2, level 4 standard. The IP4786CZ32 incorporates Transmission Line Clamping (TLC) technology on the high-speed Transition Minimized Differential Signaling (TMDS) lines to simplify routing and help reduce impedance discontinuities. All TMDS lines are protected by an impedance-matched diode configuration that minimizes impedance discontinuities caused by typical shunt diodes. The enhanced 60 mA overcurrent / overvoltage linear regulator guarantees HDMI-compliant 5 V output voltage levels with up to 6.5 V inputs. The DDC lines use a new buffering concept which decouples the internal capacitive load from the external capacitive load for use with standard Complementary Metal Oxide Semiconductor (CMOS) or Low Voltage Transistor-Transistor Logic (LVTTL) I/O cells down to 1.8 V. This buffering also redrives the DDC and CEC signals, allowing the use of longer or cheaper HDMI cables with a higher capacitance. The internal hot plug detect module simplifies the application of the HDMI transmitter to control the hot plug signal. All lines provide appropriate integrated pull-ups and pull-downs for HDMI compliance and backdrive protection to guarantee that HDMI interface signals are not pulled down if the system is powered down or enters Standby mode. Only a single external capacitor is required for operation. 2. Features and benefits HDMI 1.3a and 1.4, 340 MHz pixel clock, deep color and HDMI Ethernet and Audio return Channel (HEAC) compatible Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen and antimony (Dark Green compliant) Robust ESD protection without degradation after repeated ESD strikes Impedance matched 100 Ω differential transmission line ESD protection for TMDS lines (±10 Ω).

Application information 11.1 TMDS ESD To protect the TMDS lines and also to comply with the impedance requirements of the HDMI specification, the IP4786CZ32 provides ESD protection with matched TLC ESD structures. Typical Dual Rail Clamp (DRC) or rail-to-rail shunt structures are common for low-capacitance ESD protection (as shown on the left side of Figure 20) where the dominant factor for the TMDS line impedance dip is determined by the capacitive load to ground. Parasitic lead inductances of the packaging in this case works against the ESD clamping performance by including the ΔI/Δt reactance of the inductance into the path of the ESD shunt. The IP4786CZ32 utilizes these inherent inductances in series with the transmission line in order to present an effective capacitive load of roughly only 0.7 pF. This TLC structure minimizes the capacitive dip, for ideal signal integrity (Figure 20; right side) without complicated PCB pre-compensation. As a beneficial side effect, this enhances the ESD performance of the device as well, since the reactance of the series inductance attenuates the fast initial peak of the ESD pulse, for a lower residual pulse delivered to the Application Specific Integrated Circuit (ASIC). 018aaa102 018aaa101 a.

All rights reserved. 19 of 35 IP4786CZ32 NXP Semiconductors DVI and HDMI interface ESD and overcurrent protection 11.2 DDC circuit The DDC bus circuit integrates all required pull-ups, and provides full capacitive decoupling between the HDMI connector and the DDC bus lines on the PCB. The capacitive decoupling ensures that the maximum capacitive load is well within the 50 pF maximum of the HDMI specification. No external pull-ups or pull-downs are required. The bidirectional buffers support high-capacitive load on the HDMI cable-side. Various non-compliant but prevalent low-cost cables have been observed with a capacitive load of up to 6 nF on the DDC lines, far exceeding the 700 pF HDMI limit. The IP4786CZ32 can easily decouple this from the weaker ASIC I/O buffers, and drive the rogue cable successfully.

These I/Os are not strictly compliant with the 0.3 VDD threshold voltage levels of I2C and may miss intended logic low levels on the cable between 0.8 V and 1.5 V (typical values). This feature is also included in the CEC buffer, and thus allows standard I/O buffer cells to be used in ASICs and microcontrollers. 018aaa106 0.9 (1) VOL;VIH; VIL (V) (2) 0.7 (3) 0.5 0.3 1.6 2.6 3.6 4.6 5.6 VCC(SYS) (V) (1) VOL(max) driven to system (ASIC) side when I2C logic low (less than 0.3 × HDMI_5V0_CON) (2) VIH(min) threshold on system (ASIC) side to drive I2C logic low (3) VIL(max) threshold on system (ASIC) side to drive I2C logic low Fig 23.

The circuit generates a standard logic level from the hot plug signal. The hot plug detect circuit is pulling down the signal to avoid any floating signal. The comparator guarantees a save detection of the 2 V hot plug signal without any glitches or oscillation at the hot plug output. The IP4786CZ32 also provides an additional ESD pin to protect the reserved / HEAC pin along with hot plug detect to 8 kV IEC 61000-4-2, level 4. ESD_BYPASS VCC(5V0) HOTPLUG_DET_CON HOTPLUG_DET_SYS 100 kΩ 100 kΩ 018aaa107 Fig 24. Hot plug detect circuit 11.5 CEC The logical multidrop topology of the CEC bus can include complex physical stubs, loading cables, and interconnects that may deteriorate signal quality. The IP4786CZ32 includes a full bidirectional buffer to drive the CEC bus and isolate the CEC microcontroller or ASIC General-Purpose Input/Output (GPIO). The CEC buffer derives power from an on-board 3.3 V regulator from the VCC(5V0) domain (see Figure 25). This allows extensive system power management configurations and guarantees an HDMI compliant V(CEC_CON) on the connector, as well as the backdrive-protected 125 μA nominal CEC pull-up which does not degrade the bus when powered down. By placing the CEC microcontroller and VCC(5V0) input on a 5 V rail as shown in Figure 28, the CEC microcontroller can communicate over CEC for power commands, and then enable the HDMI port via the CEC_STBY pin, as well as the rest of the system as needed. If IP4786CZ32 Standby modes are not required, or if the Power-down modes are not desired, the CEC_STBY pin can be pulled HIGH to VCC(5V0) or VCC(SYS) for continuous HDMI and CEC operation. Strapping the CEC_STBY = VCC(SYS) = VDD of ASIC guarantees that all interface signals ending with the suffix “_SYS” on the system side will be disabled when VCC(SYS) goes low, protecting the ASIC I/O signals from exceeding its local VDD. In this mode, even if VCC(5V0) is powered, HDMI_5V0_CON go active and hot plug events can be detected only when the ASIC power supply rail is on. Strapping CEC_STBY = VCC(5V0) is the most basic configuration where the buffers are enabled whenever the local VCC(5V0) and VCC(SYS) supplies reach minimum operating levels.

CEC module 11.6 Backdrive protection The HDMI connector contains various signals which can partly supply current into an HDMI device that is powered down. Typically, the DDC lines and the CEC signals can force significant current back into the powered-down rails as shown in Figure 26, causing power-on reset problems with the system, and possible damage. The IP4786CZ32 prevents this backdrive condition whenever the I/O voltage is greater than the local supply. supply off 5V HDMI source HDMI sink backdrive current HDMI ASIC I2C-bus ASIC 018aaa109 Fig 26.

All rights reserved. 23 of 35 IP4786CZ32 NXP Semiconductors DVI and HDMI interface ESD and overcurrent protection 11.7 55 mA overcurrent / overvoltage LDO function The IP4786CZ32 integrates a complete linear output overcurrent protection to isolate faults from the source power supply, while still meeting HDMI output specifications. The Low DropOut (LDO) design provides a low-cost solution requiring just a single output capacitor (1 μF or higher, Equivalent Series Resistance (ESR) < 1 Ω), eliminating start-up and ripple concerns (see Figure 27). A typical 100 mV Vdo overcurrent-only solution would require a 5.1 V ±3 % input supply to guarantee 4.8 V to 5.3 V over 0 mA to 55 mA at the HDMI connector. The overcurrent / overvoltage feature of the IP4786CZ32 allows the use of wider tolerance input supplies up to 6.5 V while still meeting the 4.8 V to 5.3 V output limit required by HDMI. This means, for example, a cost-reduced 5.2 V ±5 % or even a 5.5 V ±10 % supply can be used with the IP4786CZ32. As with all the I/O pins, this block is ESD-protected and also provides backdrive protection in the event that a rogue HDMI sink powers the HDMI cable unexpectedly.

All rights reserved. 25 of 35 IP4786CZ32 NXP Semiconductors DVI and HDMI interface ESD and overcurrent protection 11.9 Typical application The IP4786CZ32 is designed to simplify routing to the HDMI connector, and ease the incorporation of high-level ESD protection into delicately balanced high-speed TMDS lines. These lines rely on tightly controlled microstrip or stripline transmission lines with minimal impedance discontinuities, which can deteriorate return loss, increase deterministic jitter and generally erode overall link signal integrity. Normally when designing the PCB with standard shunt ESD clamps, careful consideration must be given to manual pre-compensation of the additional load of the added ESD component. With the IP4786CZ32 TLCs, the ESD suppressor is designed to maintain the characteristic impedance of the PCB microstrip or stripline, and therefore the designer needs only be concerned with the standard-controlled impedance of the unloaded PCB lines. This simplifies the task of the PCB designer, and minimizes the tuning cycles, which are sometimes required when pre-compensation misses the mark. A basic application diagram for the ESD protection of an HDMI interface is shown in Figure 29 and Figure 30 for type-A and type-D HDMI connector versions. The optimized HVQFN32 pinning simplifies the PCB design to keep the ESD protection close to the connector where it can minimize the coupling of the ESD pulse onto other lines in the system during a strike. Due to the integrated pull-up and pull-down resistors, only two external capacitors are required to implement a fully compliant HDMI port. 001aan367 Fig 29.

Soldering of SMD packages This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 “Surface mount reflow soldering description”. 13.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both 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 Wave soldering is a joining technology in which the joints are made by solder coming from 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 ~0.6 mm 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 IP4786CZ32 Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 1 — 15 April 2011 © NXP B.V. 2011. All rights reserved. 29 of 35 IP4786CZ32 NXP Semiconductors DVI and HDMI interface ESD and overcurrent protection 13.4 Reflow soldering Key characteristics in reflow soldering are: • Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 32) than a SnPb process, thus reducing the process window • Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board • Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste 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 Table 11 and 12 Table 11. SnPb eutectic process (from J-STD-020C) Package thickness (mm) Package reflow temperature (°C) Volume (mm3) < 350 ≥ 350 < 2.5 235 220 ≥ 2.5 220 220 Table 12.
