PTN3392 2-lane DisplayPort to VGA adapter IC Rev. 4 -- 8 October 2012 Product data sheet 1. General description The PTN3392 is a DisplayPort to VGA adapter IC designed to connect a DisplayPort source to a VGA sink. The PTN3392 integrates a DisplayPort receiver and a high-speed triple video digital-to-analog converter that supports display resolutions from VGA to WUXGA (see Table 4). The PTN3392 supports either one or two DisplayPort v1.1a lanes operating at either 2.7 Gbit/s or 1.62 Gbit/s per lane. The PTN3392 has `Flash-over-AUX' capability enabling simple firmware upgradability in the field. The PTN3392 supports I2C-bus over AUX per DisplayPort v1.1a specification (Ref. 1), and bridges the VESA DDC channel to the DisplayPort Interface. The PTN3392 is designed for single supply and minimizes application costs. It can be powered directly from the DisplayPort source side 3.3 V supply without a need for additional core voltage regulator. The VGA output is powered down when there is no valid DisplayPort source data being transmitted. The PTN3392 also aids in monitor detection by performing load sensing and reporting sink connection status to the source. 2.

Functional description Referring to Figure 1 "Functional diagram", the PTN3392 converts the DisplayPort AC-coupled high speed differential signaling protocol into a VESA VSIS 1.2 compliant analog VGA signaling. The PTN3392 integrates a DisplayPort receiver (according to VESA DisplayPort v1.1a specification, Ref. 1) and a high-speed triple 8-bit video digital-to-analog converter that supports display resolution from VGA to WUXGA (see Table 4 "Display resolution and pixel clock rate"), up to a pixel clock rate of 240 MHz. The PTN3392 supports one or two DisplayPort v1.1a Main Link lanes operating at either in 2.7 Gbit/s or 1.62 Gbit/s per lane. The PTN3392 can drive up to 100 feet of analog video cable. The DisplayPort receiver comprises the following functional blocks: * * * * * * Main Link AUX CH (Auxiliary Channel) DPCD (DisplayPort Configuration Data) Monitor detection EDID handling Video DAC The RGB video data with corresponding synchronization references is extracted from the main stream video data. Main stream video attribute information is also extracted. This information is inserted once per video frame during the vertical blanking period by the DisplayPort source. The attributes describe the main video stream format in terms of geometry, timing, and color format. The original clock and video stream are derived from these main link data. The PTN3392 internal DPCD registers can be accessed by the source via the auxiliary channel. The monitor's DDC control bus may also be controlled via the auxiliary channel. A bridging conversion block translates the input DisplayPort auxiliary channel signals from the source side to the DDC signals on the sink side. The PTN3392 passes through sink-side status change (e.g., hot-plug events) to the source side, through HPD interrupts and DPCD registers. 7.1 DisplayPort Main Link The DisplayPort main link consists of doubly terminated, AC-coupled differential pair. The 50 internally calibrated termination resistors are integrated inside PTN3392. The PTN3392 supports HBR at 2.7 Gbit/s and RBR at 1.62 Gbit/s per lane. 7.2 DisplayPort auxiliary channel The AUX CH is a half-duplex, bidirectional channel between DisplayPort transmitter and receiver. It consists of one differential pair transporting self-clocked data at 1 Mbit/s. The PTN3392 integrates the AUX CH replier (or slave), and responds to transactions initiated by the DisplayPort source AUX CH requester (or master). The AUX CH uses the Manchester-II code for the self-clocked transmission of signals; every `zero' is represented by LOW-to-HIGH transition, and `one' represented by HIGH-to-LOW transition, in the middle of the bit time.

All rights reserved. 7 of 30 PTN3392 NXP Semiconductors 2-lane DisplayPort to VGA adapter IC 7.3 DPCD registers DPCD registers that are part of the VESA DisplayPort v1.1a are described in detail in Ref. 1. The following paragraphs only describe the specific implementation by PTN3392. The PTN3392 DisplayPort receiver capability and status information about the link are reported by DisplayPort Configuration Data (DPCD) registers, when a DisplayPort source issues a read command on the AUX CH. The DisplayPort source device can also write to the link configuration field of DPCD to configure and initialize the link. The DPCD is DisplayPort v1.1a compliant. It is the responsibility of the host to only issue commands within the capability of the PTN3392 as defined in the `Receiver Capability Field' in order to prevent undefined behavior. PTN3392 specific DPCD registers are listed in Table 3. 7.3.1 PTN3392 specific DPCD register settings Table 3.

All rights reserved. 9 of 30 PTN3392 NXP Semiconductors 2-lane DisplayPort to VGA adapter IC 7.3.2 I2C over AUX CH registers 7.3.2.1 I2C-bus speed control register (read only, 0000Ch) Bit or bits are set to indicate I2C-bus speed control capabilities. DisplayPort source reads register 0000Ch and sets the I2C-bus speed according to the DPCD register 00109h setting. The PTN3392 then adapts its I2C-bus bit rate to the speed set by the DisplayPort source. 7.3.2.2 I2C-bus speed control/status register (read/write, 00109h) Bit values in this register are assigned to I2C-bus speeds. Prior to software writing to this register, PTN3392 defaults to the I2C-bus speed (either 50 kbit/s or 10 kbit/s) selected by the S2 pin (Table 2). On read, the PTN3392 returns a value set to indicate the speed currently in use. On write, software provides a mask to limit the speeds to be enabled: * The PTN3392 uses the slowest speed enabled by the mask and the PTN3392 speed capabilities. * If the result of the mask with the speed capabilities is 0000 0000b, then the PTN3392 keeps the S2 setting I2C-bus speed that it is using before the software write (i.e., no change). Some specific examples are listed below for clarification purposes: * If the source writes 1111 1111b, the PTN3392 uses the lowest speed of 1 kbit/s. * If the source writes 0000 1100b, the PTN3392 uses the lower of 10 kbit/s and 100 kbit/s, i.e., 10 kbit/s. * If the source writes 0011 0000b, the PTN3392 would stay using the same I2C-bus speed that it is using before the software write (i.e., no change). For DDC communication, the PTN3392 generates defer responses to the source while the I2C-bus transfer is taking place as specified in the DisplayPort standard v1.1a. Note that when the I2C-bus bit rate is set to 1 kbit/s, each bit takes 1 ms. One byte including I2C_ACK takes 9 ms. Given this, the DisplayPort source should expect over 20 I2C_DEFER's when requesting to read a byte over I2C-bus at the slowest rate.

All rights reserved. 10 of 30 PTN3392 NXP Semiconductors 2-lane DisplayPort to VGA adapter IC 7.4 Monitor detection The PTN3392 assumes 75 double termination, as shown in Figure 6. The load sensing circuit of the PTN3392 senses a 37.5 or 75 termination respectively, when the monitor is connected or disconnected. The load-sensing circuit is active during the vertical blanking period (never during the horizontal retrace period), so that there will be no disturbance to the screen image caused by the load-sensing circuit. Upon detection of an RGB monitor being connected, the PTN3392 dynamically updates DPCD register 00200h and 00204h, to indicate the presence of a sink device being connected (see Section 7.3). After updating the DPCD register 00200h, the PTN3392 generates an IRQ request on HPD. The PTN3392 implements two different ways to handle the HPD signal. The HPD behavior is governed by the S0 pin's value after the reset and initialization sequence is completed (see Figure 3). * If S0 is tied LOW, HPD is driven HIGH irrespective of whether a VGA monitor is detected. * If S0 pin is tied HIGH, HPD is only driven HIGH when a monitor is detected. S0 = LOW S0 = HIGH Power-up Power-up HPD = 0; initialize HPD = 0; initialize HPD = 1 monitor detected? yes SINK_COUNT = 1 no yes no SINK_COUNT = 0 monitor detected? SINK_COUNT = 0 HPD = 0 SINK_COUNT = 1 HPD = 1 monitor detected changed? no no monitor detected changed? yes yes generate IRQ_HPD pulse 002aaf365 Fig 3.

All rights reserved. 11 of 30 PTN3392 NXP Semiconductors 2-lane DisplayPort to VGA adapter IC 7.4.1 S0 = logic 0 If S0 is left open-circuit (internal pull-down) (DisplayPort v1.1a compliant behavior), PTN3392 behaves as stated in VESA DisplayPort v1.1a, sections 7 and 8. PTN3392 will keep HPD LOW during its internal initialization sequence after power-up. It will then update DPCD register SINK_COUNT to the expected value, depending if a VGA monitor is detected or not, and will then assert HPD HIGH whatever is the value of SINK_COUNT register. Each time PTN3392 detects a change in the VGA monitor connection status, it will update the SINK_COUNT register accordingly, set DOWNSTREAM_PORT_STATUS_CHANGED register bit to 1 and generate IRQ_HPD pulse to signal the source about the status change. Refer to Figure 3, S0 = LOW flowchart. 7.4.2 S0 = logic 1 If S1 is tied to HIGH with external pull-up (best interoperability behavior), the PTN3392 will keep HPD LOW during its internal initialization sequence after power-up. It will then wait for a VGA monitor to be connected downstream before asserting HPD HIGH to force source waiting for a VGA monitor before starting protocol negotiations. If a VGA monitor is disconnected during normal operations, PTN3392 will assert HPD LOW so that the source will consider that no sink device is connected anymore. Refer to Figure 3, S0 = HIGH flowchart. 7.5 EDID handling Figure 4 shows a DisplayPort-to-analog video converter (or dongle) situated between the DisplayPort source and a VGA monitor. The PTN3392 converts a DP I2C Over AUX request to I2C on the monitor's DDC bus. The monitor's EDID read data is then returned to the DP source via an I2C Over AUX response issued by the PTN3392. It is the responsibility of the source to only choose video modes which are declared in the EDID and to adjust the DisplayPort link capabilities (link rate and lane count) to provide the necessary video bandwidth. The PTN3392 does not cache or modify the EDID to match the capabilities of the DisplayPort link data. If the DisplayPort source drives display modes that are not specified in the EDID mode list, the PTN3392 will not detect such conditions, and will display at its output what it is presented by the DisplayPort source. sink device DisplayPort to VGA adapter IC source device DP Tx box-to-box DisplayPort DP Rx with DPCD VIDEO DAC box-to-box legacy VGA DISPLAY WITH EDID 002aae039 Fig 4.

All rights reserved. 12 of 30 PTN3392 NXP Semiconductors 2-lane DisplayPort to VGA adapter IC 7.6 Triple 8-bit video DACs and VGA outputs The triple 8-bit video DACs output a 700 mV (peak-to-peak) analog video output signal into 37.5 load, as is the case of a doubly terminated 75 cable. The DAC is capable of supporting the maximum pixel rate supported by a two-lane DP link (240 MHz). The PTN3392 generates the RGB video timing and synchronization signals, RGB signals are then sent to the DACs for conversion to analog signals. 7.6.1 DAC reference resistor An external reference resistor must be connected between pin RSET and analog ground. This resistor sets the reference current which determines the analog output level, and is specified as 1.2 k with a 1 % tolerance. This value allows a 0.7 V (peak-to-peak) output into a 37.5 load, such as a double-terminated 75 coaxial cable. 8. Power-up and reset PTN3392 has built-in power-on reset circuitry which automatically sequences the part through reset and initialization. For proper behavior, a capacitor should be connected from the RESET_N pin to ground to slow down the internal reset pulse; 1 F capacitance is recommended. Before link is established, the PTN3392 holds VSYNC and HSYNC signals LOW and blanks the RGB signals. While the PTN3392 performs initialization, * The HPD signal is driven LOW, to indicate to the DisplayPort source that the PTN3392 is not ready for link communication * The RED, GRN, BLU and complementary outputs (RED_N, GRN_N, BLU_N) are disabled * The VSYNC and HSYNC outputs are driven LOW PTN3392 Product data sheet All information provided in this document is subject to legal disclaimers.

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". 14.1 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. 14.2 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 14.3 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 PTN3392 Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 4 -- 8 October 2012 (c) NXP B.V. 2012. All rights reserved. 23 of 30 PTN3392 NXP Semiconductors 2-lane DisplayPort to VGA adapter IC 14.4 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 9) 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 16 and 17 Table 16. 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 17.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 9.
