TC1005 BOM(1)

DC1705A-BD ESCRIPTIONUltralow Noise and Spurious Integer-N Frequency Synthesizer with Integrated VCODC1705A features the L TC®6946, an ultralow noise and spurious integer-N frequency synthesizer with integrated VCO. The VCO uses no external components and is inter-nally calibrated without external system support. There are three versions of the DC1705A, one for each version of the L TC6946. The DC1705A-A contains the L TC6946-1, the DC1705A-B incorporates the L TC6946-2 and DC1705A-C uses the L TC6946-3.Each DC1705A provides 50Ω SMA connectors for the reference frequency input, f REF, the reference output buffer (REF OUT), and the differential RF output (RF+ and RF–).A DC590 USB serial controller board is used for SPI com-munication with the L TC6946, controlled by the supplied PLLWizard™ software.Design files for this circuit board are available at /demoL, L T, L TC, L TM, Linear Technology and the Linear logo are registered trademarks and PLLWizard and QuikEval are trademarks of Linear Technology Corporation.

DC590 ConfigurationThe DC590’s QuikEval™ drivers must be installed before the DC590 will be able to communicate with the L TC6946. To configure the DC590, follow the procedure below, start-ing with step 1. If you have already installed the DC590 software previously, skip to step 5.Note: Once the QuikEval software is installed, the applica-tion does not need to be executed to run PLLWizard or to control the DC1705A.1. Do Not plug in the DC590 before running the installation program.2. Download the QuikEval installation program from /software.3. Run the QuikEval installation program and follow the on-screen instructions. More detailed installation infor-mation may be found in the DC590’s Quick Start guide.4. Exit the QuikEval program once the installation is com-plete, as it is not needed to run the PLLWizard software.5. Place the DC590 jumpers in the following positions: JP4EE Must be in the “EN” position.JP5ISO ”ON” must be selected.JP5SW ”ON” must be selected.JP6VCCIO “3.3V” must be selected. This sets the SPI port to 3.3V operation.6. Connect the DC590 to one of your computer’s USB ports with the included USB cable.2dc1705afaDEMO MANUAL DC1705AFigure 2. DC590 Jumper LocationsQUICK START PROCEDUREPLLWizard InstallationThe PLLWizard software is used to communicate with the L TC6946 synthesizer. It uses the DC590 to translate between USB and SPI-compatible serial communications formats. It also includes advanced PLL design and simula-tion capabilities. The following are the PLLWizard system requirements:• Windows Operating System: Windows XP, Windows 2003 Server, Windows Vista, Windows 7• Microsoft .NET 2.0 or later• Windows Installer 3.1 or later• Linear Technology’s QuikEval and DC590 hardware Microsoft .NETYou must have Microsoft .NET 2.0 or later installed on your computer. PLLWizard will not run without it. Note that with Windows Vista and Windows 7 have at least version 3.5 pre-installed.To manually determine your version of .NET using Win-dows XP, click Start Menu→Settings→Control Panel →Add or Remove Programs.Depending upon your .NET version, choose one of two PLLWizard setup programs, downloaded from /software.3dc1705afa4dc1705afaDEMO MANUAL DC1705A QUICK START PROCEDUREFigure 3. PLLWizard ScreenshotEither setup program will automatically install Microsoft .NET if a compatible .NET version is not found. But, the installation source depends upon which file you down-loaded from Linear Technology’s website. You should pick one of the following two choices, depending upon your version of .NET .Table 2. PLLWizard Installation FileFILE.NET 2.0 SOURCEPLLWizardSetup.exe Latest Version Downloaded from Microsoft PLLWizardSetup_net20.exe2.0 SP2 Included (Much Larger File Size)• Choose PLLWizardSetup if you have .NET 2.0 or later , have Windows Vista or Windows 7, or if you have less than .NET 2.0 but want the latest .NET installed.• Choose PLLWizardSetup_net20 if you have less than .NET 2.0, and want faster installation (no additional Microsoft downloads are needed, but the file size is much larger).The setup file will verify and/or install Microsoft .NET and install PLLWizard. Refer to the Help menu for softwareoperation.DEMO MANUAL DC1705A QUICK START PROCEDUREDC1705A Configuration1. Connect an appropriate reference frequency source (at J1) and signal analyzers (at J4 and/or J5) using the SMA connectors (see Figure 1 and the Typical DC1705A Requirements and Characteristics table).2. Choose the MUTE jumper setting: JP1 - GND/3.3V MUTE position. Select GND to mute the RF output, 3.3V to un-mute.3. Connect the GND, 3.3V and 5V banana jacks to a power supply and apply power (see Figure 1 and the Typical DC1705A Requirements and Characteristics table).4. Connect the DC590 to the DC1705A with the provided ribbon cable.5. Run the PLLWizard application.6. In PLLWizard, click File → Load Settings and point to the appropriate pllset file. For example, if you are using a 10MHz reference with a DC1705A-B to evaluate the L TC6946-2, load the “DC1705A-B (L TC6946-2) 10MHz Ref.pllset” file found in the PLLWizard installation direc-tory (typically Program Files → L TC → PLLWizard →Set Files).The red LED on DC1705A should turn on indicating that the loop is locked at 900MHz.You can then change the values of N_DIV and/or O_DIV in PLLWizard to change the output frequency.T roubleshootingIf the red LED does not illuminate, follow the instructions below:1. Verify that you are able to communicate with the DC1705A. The bottom status line in PLLWizard should read “L TC6946” and “Comm Enabled.” Refer to PLL-Wizard’s T roubleshoot and Help if not.2. Verify that the3.3V and 5V have the correct voltages on them and that the reference frequency is applied to the REF+ IN SMA input.If the red LED is on but you cannot detect an RF output, make sure jumper JP1 is at the 3.3V position. Run Help →T roubleshoot in PLLWizard if the problem is not resolved. DC1705A ReconfigurationYou can redesign the frequency plan of the DC1705A using PLLWizard. You can change the loop filter components as found using PLLWizard by reinstalling the loop filter components shown in Figure 4.Figure 4.

零件知識一. 電阻1.1 定義: 阻礙電流流過,且有一定的阻值的電子元器件,稱之為電阻.1.2 電阻用字母“R”表示1.3 電阻種類:1.3.1 碳膜電阻:用字母“RD”表示,誤差為±5%,用字母“J”表示.碳膜電阻(JP)的本體為三位數字:如2031.3.2 精密電阻:用字母“RP”表示,誤差為±1%,用字母“F”表示.精密電阻(CF)本體為四位數字:如20021.3.3 半可調電阻:用字母“VR”表示1.3.4 酸化電阻:用字母“RS”表示1.4 電阻單位的換算.電阻的單位有歐姆:Ω﹑千歐:KΩ﹑兆歐:MΩ其換算單位為:1MΩ=10³KΩ=106Ω如:203 20000Ω→20KΩ; 105 1000000Ω→1MΩ.1.5 電阻的基板圖示(AI電阻)1.6 電阻的六要素電阻在核對時,一定要有如下四素:1.6.1 阻值:即電阻阻礙量的大小,可直接從本體上認識,即其本體上的數字,讀下后再按1.4換算取最接近的單位.1.6.1.1 碳膜電阻阻值的認識:碳膜電阻本體一般為3位數,如203,即前兩位數字照寫,第三個數字是几即代表几個零,基本單位為歐姆.例:203→2 0 3→20000Ω→20KΩ照寫表3個零換算100→1 0 0→10Ω→10Ω照寫不寫無換算1.6.1.2 精密電阻阻值的認識:精密電阻本體一般為4位數,如2001 2492,即前三位數字照寫,第四個數字是几即代表几個零,基本單位也為歐姆.例:2001→200 1→2000Ω→2KΩ照寫表一個零2492→249 2→24900Ω→24.9KΩ照寫表二個零換算1.6.1.3 其它阻值的認識:有的電阻因體積太小或其它原因無法將規格印在零件本體,即需萬用表測量並核對原料盤規格方可.1.6.1.4 電阻阻值單位的選擇電阻國際單位為歐姆(Ω),常用單位為千歐(KΩ),如何用一個正確的單位來表明阻值呢?一般的,以歐姆為單位的電阻,其數字顯示不大于1000,如:不能講203為兩萬歐姆;以KΩ為單位的阻值其數字范圍為1∠@∠1000 如:不能講101為零點一千歐或105為一仟千歐.以KΩ為單位的電阻其數字不得小于1.1.6.2 誤差電阻在制造過程中其阻值不可能一模一樣,我們將電阻的實測值與定值之間的差異稱之為誤差,通常電阻誤差有F及J兩種. F=±1% J=±5% 我們一般稱±1%(F)誤差之電阻為精密電阻,±5%(J)誤差之電阻為碳膜電阻.1.6.2.1 誤差上限:其計處算分式為:定值+定值×(+誤差值)例: 203的誤差上限為: 203→20K→20K+20K*(+5%)=21K1.6.2.2 誤差下限:其計算公式為:定值+定值×(-誤差值)例:203的誤差下限為:203→20K→20K+20K×(-5%)=19K即為本體標示為203之電阻其測量值容許范圍為19K-21K之間.1.6.3 尺寸電阻的尺寸大小在SMT的置件過程中影響極大,一般地電阻大小分公制及英制兩種講法,其本質大小一樣.例:公制:1005表示電阻的長為1.0mm,寬為0.5mm,同理1608 2012等都如此.英制:0402表示電阻的長為0.04in,寬為0.02in,同理0603 0805等都如此.公英制的互換關系為:1in=25.4mm1.6.4 功率電阻阻礙電流要做功,其功率的大小直接關系產品的信耐度,一般地,電阻的功率與其制选材質﹑工藝及體積的關系,體積越大之電阻其功率越大,阻值越大.如:0805的電阻較0603而言更能增大阻值及功率,一般習慣稱0603為1/16W電阻,0805為1/8W電阻,1206為1/4W電阻,但此稱呼不絕對,如:0805的電阻亦有可能做1/4W功,且功率只可稱電阻而不可稱呼電容,如:1206大小的電容稱之為1/4W的電容即是錯誤的.二. 電容(CAPACITY)2.1 定義:在電子產品中起著濾波,消除雜質作用的元器件.2.2 電容用字母“C”表示.2.3 電容單位:通常有“F”法拉﹑“UF”微法﹑“NF”納法﹑“FP”皮法其換算單位為:1F=106UF=109NF=1012F1UF=10-6F=106PF 1PF=10-6UF=10-12F2.4 電容種類2.4.1 陶瓷電容:用字母“CC”表示,無極性.2.4.2 膽質電容:用字母“TC”表示,有方向,有極性.2.4.3 電解電容:用字母“EC”表示,有方向,有極性.2.4.4 塑膠電容:用字母“BC”表示,無極性.2.4.5 半可調電容:用字母“VC”表示,無極性.(Trimmer Cap)2.4.6 麥拉電容:用字母“MC”表示,無極性.2.5 電容的誤差:C:±0.25PF D:±0.5PFH:±3% J:±5%K:±10% X:±15%Z:-20%±80% M:±20%P:±100%-0%通有所用之誤差為:J:±5%, K: ±10%, M:±20%, Z:±80%-20%2.6 電容的耐壓:16V 25V 50V 100V 200V 500V 1000V2.7 材質分為:(亦稱耐溫)X7R Y5V Z5U NPO N330(特殊材質)其中X7R材質最好.其耐溫系數為:Y5V:-25℃+85℃X7R:-55℃+125℃Z5U:+10℃+85℃NPO:0℃±60℃如:104Z/25V NPO 0.01UF/25V NPO104表示:容值;Z表示:誤差;25V表示:耐壓;NPO表示:材質2.8 基板圖示“C”2.9 電容的六要素電容在材料核對時一定注意以下六要素:2.9.1 容值:可測量或從料盤上認知,其計算方法如:1.6.1.1碳膜電阻之計算,但其換算進位不一樣,見2.3.2.9.2 誤差:同電阻的計算誤差上﹑下限.2.9.3 耐壓:電流通過時所承受的壓降值,直接從料盤得知.2.9.4 耐溫:電容所能耐受的溫度范圍而其本身特性不受破壞.2.9.5 大小:如電阻的公﹑英制稱呼,但不能按其大小稱呼“xxw”.2.9.6 極性:電容在電路上的使用其極性很重要,主要識別如:2.4的不同種類電容極性標示不一樣,CC﹑BC﹑VC﹑MC,一般使用時均無極性.EC在本體特殊端為負極,而TC的本體特殊端為正極.三.二極體(DIODE)3.1 定義:起整流穩壓﹑截波或溫度補償等作用的元件.3.2 二極體用字母“D”表示.3.3二極體基本圖為“D”3.4 注意事項:1有方向性,有極性,所有零件本體特殊端為負極.3.4.2 標示在本體上的印碼文字或色環不能錯.3.4.3 體積大小是否與BOM 相吻合.3.4.4 二極體規格可直接看本體標示或資料顯示不用計算.3.5 二極體的分類:整流二極體:DR;開關二極體:DS;積納二極體:DZ;快速恢復二極體:DF;發光二極體:DE;橋堆二極體:DB.四.電晶體(TRANSISTOR)4.1 電晶體用字母“Q ”表示.4.2 有方向,有極性.4.3 其基本圖示為4.4 注意事項 同二極體)五.IC(INTEGRATED CIRCUIT)5.1 IC 用字母“U ”表示,起集成電路的作用,又叫集成塊.5.2 IC 的種類SOIC:兩邊腳外彎; SOJIC:兩邊腳內彎.
