SEMICONDUCTOR TECHNICAL DATA Order this document by MC145220EVK/D INTRODUCTION The MC145220EVK makes it easy to exercise features of the MC145220 and build PLLs which meet individual performance requirements. The EVK is controlled through menu driven software operating on an IBM PC or compatible. Other Motorola PLL EVKs (MC145190, MC145191, MC145192, MC145200, MC145201, MC145202) in up to three–board cascades can use the same program. Frequency defaults that apply to each are automatically selected. All board functions are controlled through the printer port of an IBM PC. Up to three different EVKs may be controlled at the same time from one printer port. The functional block diagram is given in Figure 1. This manual is divided into three sections. Section 1 describes the hardware, Section 2 describes the software, and Section 3 is the command summary.

The EVK is a complete working synthesizer, including VCOs. Board is controlled by an IBM PC–compatible computer through the printer port. Up to three boards can be operated independently through one printer port. A prototype area and mounting holes are provided for VCOs, mixers, and amplifiers. External reference input can be used. Five element loop filter is included. Frequency range of operation, step size and reference frequency can be changed in the control program. Lock Detect, Out A, and Out B on any single board are accessible through the printer port. CONTENTS OF EVALUATION KIT 1. 2. 3. 4. 5. Assembled evaluation board. Nine–foot flat cable with four DB–25 male connectors. MC145220EVK manual. 3.5″ PC–compatible disk containing compiled program. PLL device data sheets. GETTING STARTED To perform basic functions, do the following: 1. 2. 3. 4. 5. Plug in 12 volts at J8, observing the polarity marked on the board. Short circuit section 1 of the DIP switch (S1) and open circuit all other sections. Connect the supplied flat cable between the computer printer port and the DB–25 connector on the board (J9). Type PLL at the DOS prompt. Then press enter. Type the number that corresponds with the type of board given in the on–screen menu. The MC145220 may operate in single loop or dual loop mode. Then press Q. You should now see the main menu displayed. There should be a signal present at J5 if single loop, or J12 if dual loop. The frequency will be the current output frequency given in the main menu. If the signal is not on the correct frequency, check to see if your printer port address is $278 (hexadecimal 278). If not, then select the P menu item and enter the correct address. After returning to the main menu, select the I menu item to send data to the board. You should now be on frequency. MODIFICATIONS The user may modify the hardware, such as utilizing a different VCO, by using the prototyping area of the board. After such modifications are made, the default values in the software may need to be changed. This is facilitated from the ‘Select from the available options’ screen. Note that the on–board voltage regulators allow for a maximum VCO control voltage range of 0.5 – 4.5 volts.

For lowest phase noise in single or dual loop mode, a 50 Ω load must be connected to J12.

Supply current is current the board requires without user modifications. 2. Available current is the sum of currents available to the user (in the prototype area) from the 5 V and 8.5 V supply. The 12 V supply is not regulated. Current at 12 V is limited by the external power supply. If the on–board VCO and amplifier are disconnected from the power bus, more current can be drawn in the prototype area. The current flowing into U5 (the 8.5 V regulator) should not exceed 180 mA. This will limit temperature rise in U5. 3. Frequency ranges require use of the 5 V default charge pump supply voltage. 4. VCO sidebands on PLL at low step sizes (10 kHz) are limited by control line leakage of the VCO. Up to 24 nA of leakage has been seen. At higher step sizes (100 kHz and above), this effect is much less noticable. This did not affect PLL′ because its VCO leakage was less than 10 pA. 5. 10 kHz phase noise is limited by the PLL device noise. For low noise designs, the loop bandwidth is made narrower and the VCO is relied upon to provide the 10 kHz phase noise. This can be seen on the EVKs since the VCOs have much lower noise. 6. 10 MHz step, within ± 1 kHz of final frequency (’220). Due to the software architecture, when the user is measuring the switching time of a single board in dual loop mode, it takes 20 ms to load the data as compared to single loop mode, which takes 8 ms to load the data. This is a limitation of the software, not the IC. To find the actual PLL switching time, subtract 8 or 20 ms from the switching time stated in the table.

Mechanical drawing of board. MC145220 data sheet. Typical signal plots. PRODUCTION TEST After assembly is complete, the following alignment and test is performed: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. The control program is started in ’220 single loop mode. [L]! is selected to set PLL frequency to 733 MHz. Power is applied to the board. DIP switch section 1 is closed circuit with all others being open circuit. After attaching computer cable, [I]! is selected. Trim resistor VR1 is adjusted to obtain an output frequency at J5 of 733 MHz ± 500 Hz. Voltage at the control voltage test point (TP2) is measured. It must be > 0.5 V. [H]! is selected. Voltage at the control voltage test point (TP2) is measured. It must be < 4.4 V. [T]! is selected to toggle to PLL′. [L]! is selected to set PLL′ frequency to 790 MHz. Voltage at the control voltage test point (TP9) is measured. It must be > 0.5 V. [H]! is selected to set PLL′ frequency to 820 MHz. Voltage at the control voltage test point (TP9) is measured. It must be < 4.4 V. [G] is selected and the board type is changed to ’220 dual loop mode. [Q]!, then [I]!, is selected to initialize the dual mode output (J12) to 70 MHz. The frequency should be 70 MHz ± 50 Hz. If in step 5 it isn’t possible to obtain a signal on frequency, the adjustment screw in M1 may be turned for further frequency adjustment range. If neither adjustment works, [P] should be selected and the correct printer port address entered. [I]! is then selected to reload the data. BOARD OPERATION A computer is connected to the DB–25 connector J9. Data is output from the printer port. The printer card is in slot 0 using the default address in the control program. Data is sent to the PLL device (U1) through the DIP switch (S1), and 74HCT241 buffer (U2). D1, D2, D3, R7, R8, and R12 are in the data path between the ’HCT241 and PLL device. This limits the high level output voltage of the buffer. Voltage on PLL device inputs must be no greater than 0.5 V above V+. A ’220 PLL has three output lines which are routed through a 74LS126 line driver (U3) back to the computer. U2, the 74HCT241, provides isolation and logic translation for PLL input lines. Logic translation is needed from the TTL levels on the printer port to the CMOS levels on the ’220 inputs. A 12 V power supply should be used to power the board at J8 (Augat 2SV–02 connector). The 2SV–02 will accept 18–24 AWG bare copper power leads. No tools are needed for connection. If power is properly connected, LED D4 will be lit. MC145220EVK 8 MOTOROLA Power passes from J8 to U5 (LM317 regulator) configured as an 8.5 V regulator. 8.5 V powers the VCOs. Regulators U6 and U7 use the 8.5 V supply to produce 3 V and 5 V. The ’220 board can use either to power the logic and charge pump. V+ voltage is selected by J11. U6 and U7 are cascaded with U5 to equalize their individual voltage drops. The ’220 operates in both a single loop and dual loop mode. There are no component changes between the two modes. The differences are in the programming of the counters and the SMA connector that is used. The PLL loop is composed of the MC145220 (U1), 733 – 743 MHz VCO (M2), and a passive loop filter (R4, R5, C6, C7, C8). In single loop mode, output is taken from J5. A passive loop filter was used to keep the design simple, reduce noise, and reduce the quantity of traces susceptible to stray pickup. The PLL′ loop is composed of the MC145220 (U1), 790 – 820 MHz VCO (M3), and a passive loop filter (R22, R25, C24, C26, C30). In single loop mode, output is taken from J10. Dual mode output is the (f′ – f) frequency output from the mixer. It is low pass filtered (L1, L2, C15, C21, C22) then amplified (U4). The output is available at J12. Phase detector current is 2 mA. J1 is a removable jumper used for current measurement of V+. Two TCXOs, a Motorola Saber 14.4 MHz (M5), and Raltron 10.01 MHz (M1) are supplied. As shipped from the factory, the 10.01 MHz TCXO is in use. This allows both the 10 kHz and 10 Hz step sizes to be used with one TCXO. 10.01 MHz cannot be divided for larger step sizes such as 100 kHz. For larger step sizes use the Saber. Jumpers J3, J4, J13, and J14 determine which TCXO or the external reference input is in use. DUAL MODE OUTPUT The dual mode output (J12) is the difference frequency from mixing PLL and PLL′. By using a reference frequency of 10.01 MHz, PLL can be operated with a 10.01 kHz step size and PLL′ with a 10 kHz step size. If both PLL and PLL′ step down in frequency, the mixed output will step up by 10 Hz. More information on the offset reference technique is in AN1277/D, Offset Reference PLLs for Fine Resolution or Fast Hopping.

Use a reference signal at J2 which complies with data sheet requirements. Then modify the reference frequency in the program main menu to reflect the changes made (F menu item). DATA TRANSFER FROM COMPUTER TO EVK To control the serial input EVK with the parallel printer port, a conversion is done. Printer cards are designed to output eight bits through eight lines. A bit mask is used to obtain the bit combination for the three required output lines (Data, Clock, Load). As bytes are sent to the printer card in sequence, it appears to be a serial transfer. The printer port is used because data transfer using the serial port would be much slower. A standard IBM PC can support a parallel port data rate of 4.77 MHz. IBM PCs and compatibles can accept up to three printer port configurations. These ports are called LPT1, LPT2, and LPT3. Each printer port has a unique address. Two sets of addresses are in common use. One set applies to IBM PC XT, AT, and clones. The other is for the PS 2 line. To load data into the EVK, the correct address must be selected. The program default is $278. If $278 is not the address in use, it must be modified by entering the P menu item in the main menu. All allowed addresses given in hexadecimal are as follows: Label IBM PC and Clones PS 2 LPT1 278 3BC LPT2 378 378 LPT3 3BC 278 Up to three EVK boards can operate independently from one printer port. All lines on the printer port are connected to every EVK. Even with three boards operating, only three output lines (Clock, Data, and Load) from the printer card are used. If two boards are controlled together, data for the second board is received from the Output A of the first. Output A is a configurable output on ’220 devices, which in this case is used to shift data through chip 1 into chip 2. Output A and Data are connected using a printer port input line. This was done to avoid connecting extra wires. Fortunately not all port input lines are needed for computer input. Load and Clock are common to both boards. A three–board cascade is handled similarly to a two–board cascade. Out A on the first board is fed to Data on the second. Out A on the second connects to Data on the third. Instructing the program on the quantity of boards connected together allows it to modify the number of bits sent. All boards have a DIP switch S1 which gives each a unique address. The configuration menu is used to tell the program what type of board is connected at a board address. Switch positions for all possible addresses are given in Figure 3.

Switch Positions In Figure 3, DIP switch sections 6, 7, and 8 allow the computer to read Out A, Lock Detect′, or Lock Detect from the PLL device. Each of the inputs can only be read on one board at a time, but each item could be read on a different board. In a three–board cascade, Out A could be read from the first board, Out B from the second, and Lock Detect from the third. There is no way to determine the board address of a particular input with software. The control program does not make use of these inputs; however, source code could be modified as required.

Board Type Board Description MC145190 MC145191 MC145192 Low voltage version of the ’191 MC145200 MC145201 MC145202 Low voltage version of the ’201 MC145220 in Single Loop Mode MC145220 in Dual Loop Mode PURPOSE The user guide for the MC145xxx PLL software familiarizes the user with the use and capabilities of the program referred from here on as PLLDEMO Version 4.0. The guide covers the user interface and a summary of the commands that are available. The user should read the data sheet of the PLL frequency synthesizer of interest before using the software. DESCRIPTION The PLL software: • is a Pascal program developed with Borland Turbo Pascal v7.0. • runs under MS–DOS. • is a character–based, menu–driven program. USER INTERFACE The user interface consists of numerous character–based, menu–driven screens which are displayed below. Each screen is shown, along with a description of its purpose. Note that all screen shots shown are a representative sample of the program. They are provided to familiarize the end user with the program. INSTALL To install this program, create a directory called “PLLEVAL”. Change directories into “PLLEVAL” and copy PLL.exe into this directory. MC145220EVK 14 MOTOROLA UNINSTALL To uninstall this program, change directories into “PLLEVAL” and type “erase*.*”. After this command, change out of directory “PLLEVAL” and type “erase PLLEVAL”. Note: If you are in Windows 3.X or Windows 95, this program adds no entries into .ini or Registry files. It is recommended that you have the PLL program running while you are reviewing this manual. Due to the number of screens that may be involved in your evaluation, following the connections, screens, and commands is easier when the manual and program are used together. CONVENTIONS Some of the PLLDEMO screens are necessarily “busy”. Because of this, the program follows several conventions to help the user quickly absorb the screen information. These conventions are briefly described on a help screen that is available throughout the program. Type the help command, [?], at any time to view the help screen. The conventions are as follows: 1. Command keys are surrounded by [ ]s. Type the letter between the [ ]s to execute the command. [ ]s are followed by a description of the command. 2. [–] indicates a command not available to the user. Commands become available when they are applicable to the currently targeted board. 3. [ ]s followed by an ! indicate the command will execute immediately. Otherwise a submenu is displayed from which further choices may be made. 4. If no changes are desired to an input field, leave the field blank. The previous value will then be used for that field. Type the TAB key to move to the next input field, or shift–TAB to move to the prior input field. Type RETURN to store the new input values while remaining on the same screen. Type Q to store the new values and return to the prior screen. 5. All numbers are entered as decimal values unless otherwise noted. A $ followed by a value indicates the value is in hexadecimal format. The output port address is in hexadecimal format. 6. The second line from the top of screen (screen title) states the purpose of the screen. 7. Screen information that can be changed by the user is displayed in bold or reverse video. 8. Commands are case independent. X is the same as x. 9. Frequencies are entered as two numbers, and displayed as one. The two input numbers represent the desired frequency in MHz, and in kHz. These input values are added together to obtain the final frequency. Leave either input field blank to retain the prior value for that portion of frequency. ALERT AND ERROR MESSAGES This program contains two types of messages that appear when conditions warrant. (See Table 2.) 1. Alert Messages. These messages alert you that though the current values are valid, you are unable to continuously increment the A and N counters. Hit any key to remove these messages and continue with the program.

This screen is used to define which boards are connected to the LPT1 printer port of the computer. Refer to the hardware setup section to determine how to cascade the evaluation boards. This screen is also available from the main menu. The user may return to this screen by depressing [Q] to change the boards that are connected to the computer. The screen is divided into two sections. The upper section shows the current board type settings while the lower section allows the user to define a board’s type and position in the cascade connection. Notice the section labeled ‘Available Boards:’ shows three labels, one for each board that may be cascaded. When the program first starts up it shows ‘N/A’ (not applicable) after each label. The user must enter the boards contiguously. Initially the program requests for the user to enter board A’s type. This is signified by A (in the screen below) being set to A. The user can the select the board type for board A by typing the corresponding command. Once board A’s type is selected, A automatically increments to B and the process may be repeated. Once all boards have been correctly defined, the user may select [Q] which sends default data to the boards and continues to the next screen. NOTE: Before selecting [Q], the user should insure that the DIP switch settings shown in Figure 2 are correct. If a board is incorrectly identified, select the board that is not correctly defined by typing the corresponding board letter ([A], [B], or [C]). The user may then reselect the board’s type. Once the board has been identified, the user may select the letter ([A], [B], or [C]) of the board followed by [S] to change hardware– dependent variables for that board. [X] can be selected to exit the program completely. [?] can be selected to view the help screen.

MOTOROLA MC145220EVK 19 ‘Select from the available options’ This is the main screen of the program. This is where the user enters commands to demonstrate the capabilities of the various boards connected to the computer. The title of the screen is ‘Select from the available options’. This screen is broken down into three sections: ‘Available Boards’ This section displays the board types that are connected to the computer. It also designates which board is the currently selected ‘target’ board. This is the board that will receive the commands from ‘MC145xxx Commands’ section. This section also provides the ability to change the targeted board. Type the target board command ([A], [B], or [C]) to target that particular board. ‘MC145xxx Commands’ This section is further divided into three subsections. Each subsection contains commands that can be sent to the ‘target’ board to demonstrate its capabilities. Each of these commands is described in full in the Command Summary. The first subsection, ‘MC145xxx Frequency Commands’, contains commands that are used to modify the PLL frequency in some way. These commands are available for all possible target board types. In the top line of this section, ‘Current Output Frequency is 70 MHz’ designates what the frequency is for the currently targeted board. This value is dynamic. On the lines below this, 60 MHz is the current setting for the default low frequency. 70 MHz is the current setting for the default medium frequency. 80 MHz is the current setting for the default high frequency. The second subsection, ‘MC145xxx Additional Commands’, contains commands that are used to further modify the currently targeted board. These commands also work with all of the MC145xxx board types. The third subsection, ‘MC145220 EVK – Single Specific Commands’, are only displayed when the MC145220EVK in single loop mode is the currently targeted board. This section shows commands that are specific to this board. This is required since this board contains the equivalent of two PLLs. The command letter for ‘Set target PLL on board’ is [T]!. In single loop mode, the user may toggle between PLL and PLL′ on the MC145220EVK by using this command. Feedback is given to the user as to whether PLL or PLL′ will be accessed. See near the top of the screen on the line titled “Available Boards - Current target board is: ...” ‘Initialization/System Setup Commands’ This section contains commands that are used to initialize all boards connected to the computer or to set up the computer.

This will place you in the “Select from the available options” screen. The command [O] is on this screen. See page 21 of this document for a sample screen shot of this command. This command prompts the user to input a decimal value in MHz and kHz to set the targeted board frequency. The program default PLL output frequency is displayed along with the current value. The user may leave the output frequency value as is by entering return without entering a value. The program validates the entered frequency by checking to ensure that the value is a multiple of the board’s current step size and that the entered frequency / frequency step size is ≥ 4032. The program accepts total divide values < 4032 if N ≥ A. (Total divide must be ≤ 262,143 for all PLLs.) N*P+A = total divide (p = prescale = 64 for ’191), (p = prescale = 32 or 64 for ’220) A further check is made to ensure that the entered frequency is within the capability of the currently targeted demonstration board. (See Table 7.) Frequencies outside the range are allowed for users who use their own VCO. Note in ’220 dual mode, frequencies outside the program default will not be accepted due to the complexity of error checking the results.

MOTOROLA MC145220EVK 37 [F] Set REFin frequency and channel spacing To access this command in the program, select a board in the “Define boards to program” screen and then press [Q]! . This will place you in the “Select from the available options” screen. The command [F] is on this screen. See page 23 of this document for a sample screen shot of this command. This command prompts the user to input two values. First, a decimal value, in the form of XX MHz + XXX kHz, to set the reference frequency of the targeted board. The program default frequency is displayed along with the current value. The user may leave the reference frequency value as is by entering return. A second input, in the form of XX MHz + XXX kHz, sets the channel spacing (step size) of the targeted board. The program default step size is displayed along with the current value. The user may leave the step size as is by entering return. The inputs are validated by checking that the step size remains ≤ 2 MHz (≤ 1 MHz for the ’220) for all boards. The entered frequency is validated to ensure that the new reference frequency / new step size is < 8191 and is an even multiple of the new channel spacing. Finally, the RCOUNTER of the R register is set with the value of (new reference frequency / new channel spacing) and R register is written to the targeted board. Then the ACOUNTER and NCOUNTER are reset to the previous frequency using the new channel spacing (previous frequency / new channel spacing) and the A register is written out. Note that due to the complexity of error checking in dual mode, REFin frequency and channel spacing may not be modified.
