INTRODUCTION
The MC145192EVK and MC145202EVK are two versions of one board with a few component changes. They allow users to exercise features of both devices and to build PLLs which meet individual perfor­mance requirements. The control program works with any board and can be used with other Motorola PLL devices (MC145190, MC145191, MC145200, MC145201, MC145220*). It will select frequency de­faults that apply to each. 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 two sections. Section 1 describes the hardware and Section 2 covers the software control program.

TYPICAL PERFORMANCE
Common to both kits, unless noted. Typical performance applies only to the configuration as shipped. The MC145192EVK is shipped with VCC = 3 V and VPD = 5 V. The MC145202EVK is shipped with VCC = 5 V and VPD = 5 V.

NOTES:
1. 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 U3 (the 8.5 V regulator) should not exceed 180 mA. This will limit temperature rise in U3.
3. Frequency ranges require use of the 5 V default charge pump supply voltage.
4. 10 kHz phase noise is limited by the PLL device noise. For low noise designs, the loop bandwidth is made more narrow and the VCO is relied upon to provide the 10 kHz phase noise. This can be seen on the EVKs since the VCO has much lower noise.
5. 10 MHz step, within ± 1 kHz of final frequency (’192). 20 MHz step, within ± 2 kHz of final frequency (’202).

SUPPORT MATERIAL
To provide further information, the following documents are included:
1. Schematic diagram of ’192/202EVK.
2. Separate Bill of Materials for each board.
3. Parts layout diagram.
4. Mechanical drawing of board.
5. MC145192 and MC145202 data sheets.
6. Printer port diagram.
7. Typical signal plots for each type of EVK.
PRODUCTION TEST
After assembly is complete, the following alignment and test is performed on ’192EVK (or ’202EVK):
1. The control program is started in single board ’190EVK (’200EVK) mode.
2. L menu item is selected.
3. Power is applied to the board. DIP switch section 1 is closed circuit with all others being open circuit.
4. After attaching computer cable, menu item I is selected.
5. Trim resistor VR1 is adjusted to obtain an output frequency at J8 of 740.999 – 741.001 MHz (1481.998 – 1482.002 MHz).
6. Voltage at the control voltage test point is measured. It must be 2.5 – 3.1 V.
7. When testing more than 1 board, steps 3 – 6 are repeated.
If in step 5 it isn’t possible to obtain a signal on frequency, menu item P should be selected and the cor­rect printer port address entered. Menu item I would then be selected to reload the data.
BOARD OPERATION
A computer is connected to the DB–25 connector J5. 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 (U5). D2, D3, D4, R19, R20, and R21 are in the data path between the 74HCT241 and PLL devices. This limits the high level output voltage of the buffer. Voltage on the PLL device inputs must not be greater than 0.5 V above VCC. A ’192/202 PLL has three output lines which are routed through a 74LS126 line driver (U2) to the computer.
U5, the 74HCT241, provides isolation, logic translation and a turn–on delay for PLL input lines. Logic translation is needed from the TTL levels on the printer port to the CMOS levels on the ’192/202 inputs. Turn–on delay is used to ensure the power–on reset functions properly. The enable line to the PLL must be held low during power–up.
Power passes from J6 to U3 (LM317 regulator) configured as an 8.5 V regulator. Both boards use 8.5 V to power the VCO and RF amplifier. Regulators U4 and U7 use the 8.5 V supply to produce 3 V and 5 V. The ’192 always uses 3 V to power logic and 5 V to power the charge pump, while the ’202 can have either power both the logic and charge pump. J3 and J4 are jumpers which select voltages for the logic and charge pump supplies. U4 and U7 are cascaded with U3 to equalize their individual voltage drops.
The PLL loop is composed of the PLL device (U1), 733 – 743 MHz VCO (M1), passive loop filter (R11, R12, C4, C5, C6) and second harmonic filter amplifier (U6). A passive loop filter was used to keep the

MOTOROLA
design simple, reduce noise, and reduce the quantity of traces susceptible to stray pickup. About 56 dB rejection of fundamental and 23 dB gain is provided by the harmonic filter amplifier. This allows the ’202 to lock at 1466 – 1486 MHz.
A single VCO model is used for both boards. It is an internal Motorola part which is not sold for other applications. The ’192 operates at half the output frequency and step size of the ’202. This allows the same loop filter components to be used. RF is fed to the PLL chip Fin input through voltage dividers R14 and R10. These two resistors terminate the PLL chip RF input with 50 ohms and provide isolation.
Both boards use a phase detector current of 2 mA. J1 and J2 are removable jumpers and cut traces. They are used as connection points for a current measurement of VPD or VCC. A potentiometer VR1 is used to set M2 (14.4 MHz TCXO) on frequency.

EXTERNAL REFERENCE INPUT
As shipped, all boards are configured for a 14.4 MHz TCXO (supplied). To use an external reference, disconnect J13 and connect J9. Use a reference signal at J10 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 is 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 cards. These ports are called LPT1, LPT2, and LPT3. Each printer card has jumpers or DIP switches on it to set 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, which is LPT1 in a clone. If $278 is not the address in use, it must be modified by entering the O menu item in the main menu. All allowed addresses given in hexadecimal are as follows:

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 2.

In Figure 2, DIP switch sections 6, 7, and 8 allow the computer to read Out A, Out B 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 in software the board address of a particular input. The control program does not make use of these inputs. Pin assignment on the printer port connector is:

* The ’220 is not available in Rev. 2.5 software.
Most of these ICs are provided on an evaluation circuit board to allow the easy demonstration of the PLL capabilities.
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 PLL Version 3.0. 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 COMMENTS
Comments on this program may be faxed to MDAD Development Tools Group at (512) 933–8570.

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.
CONVENTIONS
Some of the PLL 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 indi– cates 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 repre– sent 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 fre– quency.

SCREENS Screen #1 ‘Define boards to program’
The first screen the user sees when the program begins has a screen title of ‘Define boards to 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 (screen #2). The user may return to this screen 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. See screen #1b.
[X] can be selected to exit the program completely. [?] can be selected to view the help screen.

Screen #2 ‘Select from the available options’
Screen #2 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:
Section #1, ‘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 section #2. 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.
Section #2, ‘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
746 MHz’
designates what the
frequency is for the currently targeted board. This value is dynamic. On the lines below this,
741 MHz
is the current setting for the default low frequency.
746 MHz
is the current setting for the default medium frequency.
751 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: ...”
Section #3, ‘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.

COMMAND SUMMARY
NOTE: MC145220 selections are not implemented in rev. 2.5.
[A]! Set board A as target
This command sets the target board to the board shown as A. This means that the commands that follow will affect board A only. The user is informed of, and may modify, the target board in any screen of the program except the help screen.
This is strictly an internal program command and has no effect on the MC145xxx EVKs connected to the computer.
[B]! Set board B as target
This command sets the target board to the board shown as B. This means that the commands that follow will affect board B only. The user is informed of, and may modify, the target board in any screen of the program except the help screen.
This is strictly an internal program command and has no effect on the MC145xxx EVKs connected to the computer.
[C]! Set board C as target
This command sets the target board to the board shown as C. This means that the commands that follow will affect board C only. The user is informed of, and may modify, the target board in any screen of the program except the help screen.
This is strictly an internal program command and has no effect on the MC145xxx EVKs connected to the computer.
[L]! Set to low freq.
This command is used to set the frequency of the currently selected board to the currently defined low value. This value can be changed via the [W] command.
This is accomplished by correctly adjusting the A register for the targeted board.
If the current EVK is the MC145220 and the board is in DUAL mode, then the currently targeted PLL on the board is set to the specified low frequency. Otherwise, if the board is in SINGLE mode, both on– board PLLs are set to the new frequency.
[M]! Set to medium freq.
This command is used just as the [L]! command except that the defined medium frequency value is used. This default value can be changed by selecting command [N]. Reference [L]! command for further de­tails.
[H]! Set to high freq.
This command is used just like the [L]! command except that the defined high frequency value is used. This default value can be changed by selecting command [W]. Reference [L]! command for further de­tails.

[W] Change default low frequency
This command prompts the user (screen #5) to input a decimal value in MHz for the default low frequen­cy. The program default low value is displayed along with the current value. The user may leave the low frequency value as is by entering return without a value. The program low default value is dependent on the targeted board type (see Table 2).
This value is not sent to the board immediately . It is the value that is sent to the board when the [L] com­mand is executed.

This command prompts the user (screen #5) to input a decimal value in MHz for the default high frequen­cy. The program default high value is displayed along with the current value. The user may leave the high frequency value as is by entering return without a value. The program high default value is dependent on the targeted board type (see Table 4).
This value is not sent to the board immediately . It is the value that is sent to the board when the [L] com­mand is executed.

[U]! Step frequency up by step size
This command increments the NCOUNTER and ACOUNTER fields of the A register for the currently targeted board. This steps up the PLL’s frequency by the current step size for the board.
If the currently selected board is an MC145220 in DUAL mode, then the currently targeted PLL on the board is “stepped”. If the MC145220 is in SINGLE mode, then both PLLs on the board are “stepped”.
[D]! Step frequency down by step size
If the currently selected board is an MC145220 in DUAL mode, then the currently targeted PLL on the board is “stepped”. If the MC145220 is in SINGLE mode, then both PLLs on the board are “stepped”.
[O] Set PLL output frequency
This command prompts the user (screen #3) 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). A further check is made to ensure that the entered frequency is within the capability of the currently tar-
geted demonstration board (see Table 5). Frequencies outside the range are allowed for users who use their own VCO.

Once validated, the NCOUNTER and ACOUNTER fields of the A register are appropriately modified to set the PLL frequency for the targeted board to the specified value.
[F] Set REFin frequency and channel spacing
This command prompts the user (screen #4) 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.
