receiver that is used in digital flat panel display systems to receive and decode TMDS-encoded RGB pixel data streams.In a digital display system a host,usually a PC or workstation,contains a TMDS-compatible transmitter that receives 24-bit pixel data along with appropriate control signals and encodes them into a high-speed low-voltage differential serial bit stream fit for transmission over a twisted-pair cable to a display device.The display device,usually a flat-panel monitor,10Submit Documentation FeedbackCopyright ©2000–2013,Texas Instruments IncorporatedProduct Folder Links:TFP401TFP401ATFP401TFP401A SLDS120E–MARCH2000–REVISED JULY2013 requires a TMDS-compatible receiver like the TI TFP401/401A to decode the serial bit stream back to the same 24-bit pixel data and control signals that originated at the host.This decoded data can then be applied directly to the flat-panel drive circuitry to produce an image on the display.Because the host and display can be separated by distances up to5meters or more,serial transmission of the pixel data is preferred.To support modern display resolutions up to UXGA,a high-bandwidth receiver with good jitter and skew tolerance is required.TMDS PIXEL DATA AND CONTROL SIGNAL ENCODINGTMDS stands for transition-minimized differential signaling.Only one of two possible TMDS characters for a given pixel is transmitted at a given time.The transmitter keeps a running count of the number of ones and zeros previously sent,and transmits the character that minimizes the number of transitions to approximate a dc balance of the transmission line.Three TMDS channels are used to receive RGB pixel data during active display time,DE=high.The same three channels also receive control signals,HSYNC,VSYNC,and user-defined control signals CTL[3:1].These control signals are received during inactive display or blanking-time.Blanking-time is when DE=low.The following table maps the received input data to the appropriate TMDS input channel in a DVI-compliant system.RECEIVED PIXEL DATA OUTPUT PINSINPUT CHANNELACTIVE DISPLAY DE=HIGH(VALID FOR DE=HIGH)Red[7:0]Channel-2(Rx2±)QE[23:16]QO[23:16]Green[7:0]Channel-1(Rx1±)QE[15:8]QO[15:8]Blue[7:0]Channel-0(Rx0±)QE[7:0]QO[7:0]RECEIVED CONTROL DATA OUTPUT PINSINPUT CHANNELBLANKING DE=LOW(VALID FOR

CTL[3:1]and ignores CTL0characters.CTL0is not available as a TFP401/401A output.The TFP401/401A discriminates between valid pixel TMDS characters and control TMDS characters to determine the state of active display versus blanking,i.e.,the state of DE.TFP401/401A CLOCKING AND DATA SYNCHRONIZATIONThe TFP401/401A receives a clock reference from the DVI transmitter that has a period equal to the pixel time, t pix.The frequency of this clock is also referred to as the pixel rate.Because the TMDS encoded data on Rx[2:0] contains10bits per8-bit pixel,it follows that the Rx[2:0]serial bit rate is10times the pixel rate.For example,the required pixel rate to support a UXGA resolution with60-Hz refresh rate is165MHz.The TMDS serial bit rate is 10×the pixel rate,or1.65Gb/s.Due to the transmission of this high-speed digital bit stream,on three separate channels(or twisted-pair wires)of long distances(3–5meters),phase synchronization between the data steams and the input reference clock is not assured.In addition,skew between the three data channels is common.The TFP401/401A uses a4×oversampling scheme of the input data streams to achieve reliable synchronization with up to1-t pix channel-to-channel skew tolerance.Accumulated jitter on the clock and data lines due to reflections and external noise sources is also typical of high-speed serial data transmission;hence,the TFP401/401A design for high jitter tolerance.The input clock to the TFP401/401A is conditioned by a phase-locked loop(PLL)to remove high-frequency jitter from the clock.The PLL provides four10×clock outputs of different phase to locate and sync the TMDS data streams(4×oversampling).During active display,the pixel data is encoded to be transition-minimized,whereas in blank,the control data is encoded to be transition-maximized.A DVI-compliant transmitter is required to transmit in blank for a minimum period of time,128t pix,to ensure sufficient time for data synchronization when the receiver sees a transition-maximized code.Synchronization during blank,when the data is transition-maximized,ensures reliable data-bit boundary detection.Phase synchronization to the data streams is unique for each of the three input channels and is maintained as long as the link remains active.Copyright©2000–2013,Texas Instruments Incorporated Submit Documentation Feedback11Product Folder

single-ended termination to AV DD.The TFP401/401A is internally optimized using a laser trim process to precisely fix the impedance at50Ω.The device functions normally with or without a resistor on the EXT_RES pin,so it remains drop-in compatible with current sockets.The fixed impedance eliminates the need for an external resistor while providing optimum impedance matching to standard50-ΩDVI cables.Figure14shows a conceptual schematic of a DVI transmitter and TFP401/401A receiver connection.A transmitter drives the twisted-pair cable via a current source,usually achieved with an open-drain type output driver.The internal resistor,which is matched to the cable impedance at the TFP401/401A input,provides a pullup to AV DD.Naturally,when the transmitter is disconnected and the TFP401/401A DVI inputs are left unconnected,the TFP401/401A receiver inputs pull up to AV DD.The single-ended differential signal and full-differential signal is shown in Figure15.The TFP401/401A is designed to respond to differential signal swings ranging from150mV to1.56V with common-mode voltages ranging from(AV DD–300mV)to(AV DD–37mV).Figure14.TMDS Differential Input and Transmitter ConnectionFigure15.TMDS InputsTFP401A INCORPORATES HSYNC JITTER IMMUNITYSeveral DVI transmitters available in the market introduce jitter on the transmitted HSYNC and VSYNC signals during the TMDS encryption process.The HSYNC signal can shift by one pixel position(one clock)from nominal in either direction,resulting in up to two cycles of HSYNC shift.This jitter carries through to the DVI receiver,and if the position of HSYNC shifts continuously,the receiver can lose track of the input timing,causing pixel noise to occur on the display.For this reason,a DVI-compliant receiver with HSYNC jitter immunity should be used in all displays that could be connected to host PCs with transmitters that have this HSYNC jitter problem.12Submit Documentation Feedback Copyright©2000–2013,Texas Instruments IncorporatedProduct Folder Links:TFP401TFP401ATFP401TFP401A SLDS120E –MARCH 2000–REVISED JULY 2013The TFP401A integrates HSYNC regeneration circuitry that provides a seamless interface to these noncomplianttransmitters.The position of the data enable (DE)signal is always fixed in relation to data,irrespective of thelocation of HSYNC.The TFP401A receiver uses the DE and clock signals to recreate stable vertical andhorizontal sync signals.The circuit filters the HSYNC output of the receiver,and HSYNC is shifted to the nearesteighth bit boundary,producing a stable output with respect to data,as shown in Figure 16.This ensures accuratedata synchronization at the input of the display timing controller.This HSYNC regeneration circuit is transparent to the monitor and need not be removed even if the transmittedHSYNC is stable.For example,the PanelBus line of DVI 1.0compliant transmitters,such as the TFP6422andTFP420,do not have the HSYNC jitter problem.The TFP401A operates correctly with either compliant ornoncompliant transmitters.In contrast,the TFP401is ideal for customers who have control over the transmitportion of the design,such as bundled system manufacturers and for internal monitor use (the DVI connectionTFP401/401A MODES OF OPERATIONThe TFP401/401A provides system design flexibility and value by providing the system designer withconfigurable options or

CONFIGURATIONSThe TFP401/401A provides flexibility by offering various output driver features that can be used to optimizepower consumption,ground bounce,and power-supply noise.The following sections outline the output driverfeatures and their effects.Output Driver Power Down (PDO =low).Pulling PDO low places all the output drivers,except CTL1andSCDT,into a high-impedance state.The SCDT output,which indicates link-disabled or link-inactive,can be tieddirectly to the PDO input to disable the output drivers when the link is inactive or when the cable is disconnected.An internal pullup on the PDO pin defaults the TFP401/401A to the normal nonpower-down output drive mode ifleft unconnected.Copyright ©2000–2013,Texas Instruments Incorporated Submit Documentation Feedback13Product

Setting STAG=low time-staggers the even-and odd-pixel outputs so as to reduce the amount of instantaneous current surge from the power supply.Depending on the PCB layout and design,this can help reduce the amount of system ground bounce and power-supply noise.The time stagger is such that in2-pixel/clock mode,the even pixel is delayed from the latching edge of ODCK by0.25t cip.(t cip is the period of ODCK.The ODCK period is 2t pix when in2-pixel/clock mode.)Depending on system constraints of output load,pixel rate,panel input architecture,and board cost,the TFP401/401A drive-strength and staggered-pixel options allow flexibility to reduce system power-supply noise, ground bounce,and EMI.Power Management.The TFP401/401A offers several system power-management features.The output driver power down(PDO=low)is an intermediate mode which offers several uses.During this mode, all output drivers except SCDT and CTL1are driven to a high-impedance state while the rest of the device circuitry remains active.The TFP401/401A power down(PD=low)is a complete power down in that it powers down the digital core,the analog circuitry,and output drivers.All output drivers are placed into a Hi-Z state.All inputs are disabled except for the PD input.The TFP401/401A does not respond to any digital or analog inputs until PD is pulled high.Both PDO and PD have internal pullups,so if left unconnected they default the TFP401/401A to normal operating modes.Sync Detect.The TFP401/401A offers an output,SCDT,to indicate link activity.The TFP401/401A monitors activity on DE to determine if the link is active.When1million(1e6)pixel clock periods pass without a transition on DE,the TFP401/401A considers the link inactive,and SCDT is driven low.While SCDT is low,if two DE transitions are detected within1600pixel clock periods,the link is considered active,and SCDT is pulled high. SCDT can be used to signal a system power management circuit to initiate a system power down when the link is considered inactive.The SCDT can also be tied directly to the TFP401/401A PDO input to power down the output drivers when the link is inactive.It is not recommended to use SCDT to drive the PD input,because once in complete power-down,the analog inputs are ignored and the SCDT state does not change.An external system power-management circuit to drive PD is preferred.TI PowerPAD100-TQFP PACKAGEThe TFP401/401A is packaged in TI's thermally enhanced PowerPAD100-TQFP packaging.The PowerPAD package is a14-mm×14-mm×1-mm TQFP outline with0.5-mm lead pitch.The PowerPAD package has a specially designed die mount pad that offers improved thermal capability over typical TQFP packages of the same outline.The TI100-TQFP PowerPAD package offers a back-side solder plane that connects directly to the die mount pad for enhanced thermal conduction.Soldering the back side of the TFP401/401A to the application board is not required thermally,because the device power dissipation is well within the package capability when not soldered.Soldering the back side of the device to the PCB ground plane is recommended for electrical considerations. Because the die pad is electrically connected to the chip substrate and hence to chip ground,connection of the PowerPAD back side to a PCB ground plane helps to improve EMI,ground bounce,and power-supply noise performance.Table1outlines the thermal properties of the TI100-TQFP PowerPAD package.The100-TQFP non-PowerPAD package is included only for reference.14Submit Documentation Feedback Copyright©2000–2013,Texas Instruments IncorporatedProduct Folder Links:TFP401TFP401ACopyright©2000–2013,Texas Instruments Incorporated Submit Documentation Feedback15Product Folder Links:TFP401TFP401APACKAGING INFORMATION(1) The marketing status values are defined as follows:ACTIVE: Product device recommended for new designs.LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.NRND: Not recommended for new designs.

Digi-Wave Connect DWD 401 用户指南说明书
Digi-Wave Connect DWD 401Digi-Wave Connect is an analog audio cable converter box that sends audio to and from an existing Digi-Wave 400 system. By connecting your Digi-Wave Connect to your local audio system, you can transmit sound from your audio equipment to your Digi-Wave group, or output the audio from your Digi-Wave group to your local sound system. The USB cable connects the audio in, audio out from the Digi-Wave DLT Transceiver and provides it to the Digi-Wave Connect.Powering On and ChargingConnect the power cable to the power port on the Digi-Wave connect.Once USB cable is connected to the DLT Transceiver from the Digi-Wave Connect, the LED on the top of the DLT transceiver will light up. The device will charge and stay charged while connected. Connecting a DLTA USB 3.1 typeC cable is included with the Digi-Wave Connect and is used to connect a DLT transceiver to the Digi-Wave Connect.NOTE: A Standard USB 2 type C will not work.

DP-401 电话等待音乐专用播放器
使用说明书
安装导引
步骤1：安装SD卡
在安装SD卡之前，必须先把音档存入该卡。
旋转VOL旋钮至〝OFF〞方向，直到电源指示灯熄灭，也可采用直接拔除电源(如果〝VOL〞音量已设定在理想位置，不考虑改变它的情况下)，在断电状态下，滑开SD卡的盖子，把SD卡反面朝上插入。
若要拔下SD卡，再向里面推入，SD 卡会自动弹出，盖上SD卡的盖子。
步骤2：连接电话线与电源
接通电源适配器，将音频线的3.5音频头插入O/P接口，另一头接到三通连接线的电话插口。
将电话进线从电话机上拔出，接入三通连接线的另一个电话插口。
将三通连接线所带的电话水晶头接到电话机的电话线插口上。
可参照接线示意图。
步骤3：打开电源开关调整输出音量
用〝VOL〞把电源打开并调整到适当输出音量，按下一键切换按钮，声音自动播放。
一键切换按钮用于切换通话模式与音乐播放模式。
步骤4：选择播放轨号
最高可储存99轨的语音资料。
按一次〝Change〞按钮，可跳到下一轨。
如果是在最后一轨时，按下〝Change〞按钮则跳到第一轨。
DP-401具有记忆作用，断电之前所播放的轨号，重新通电后会自动恢复播放此轨号的音乐。
面板LED指示当前播放轨号。
接线示意图
使用方法：
若通话中需要对方等待时，请按下一键切换按钮，本地的声音不能传递到对方，此时对方听筒中播放预存的音乐。
再次按下一键切换按钮，按钮弹起则恢复通话。
文件名(轨号)规则：
声音档案可以是MP3或WAV文件，在同一片SD卡上这两种档案可同时存在，立体声音档的左、右声道会被混合成单音输出。
必须在文件名前加上一个3位数的数字， 例如： 001anyname.mp3 为第一轨，
088anothername.wav为第88轨。
如果文件名超过99则不被接受（轨号的建立可不连续）
产品特点：
•永久保存：SD卡存储，100%数字设计，无须录音带或CD
•使用广泛：可以与任何模拟电话机搭配
•一键切换：电话通话与音乐播放一键切换

故障检修
1. 如果没有声音输出，将音频口O/P接口的连接线拔出，按下一键切换按钮，确认是否有声音。
若无声音输出：
a)请检查输出开关〝VOL〞是否打开。
b)请检查切换按钮是否切换成音乐播放模式，按下按钮为音乐播放模式，弹起则为通话模式。
c)如果听不到声音输出，可能是SD卡没有插好，请先关电后重插SD卡，再重新打开电源。
2. 播放的轨号不对时
按〝Change〞按钮去选取正确轨数
3. 声音质量不理想
可能是因声音输出过大，可把〝VOL〞旋钮调小。
