Text in bold refers to items directly from the EV kit software. Text in bold and underlined refers to items from the Windows operating system. Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation: 1. Visit www.maximintegrated.com/evkitsoftware to download the latest version of the EV kit software, 7060Rxx.ZIP. Save the EV kit software to a temporary folder and uncompress the ZIP file. 2) Install the EV kit software and the USB driver on your computer by running the INSTALL.EXE program inside the temporary folder. The program files are copied to your PC and icons are created in the Windows Start | Programs menu. During software installation, some versions of Windows may show a warning message indicating that this software is from an unknown publisher. This is not an error condition and it is safe to proceed with installation. Administrator privileges are required to install the USB device driver on Windows. 3) Verify that all jumpers are in their default positions, as shown in Tables 1, 2, and 3. 4) Connect the USB cable from the PC to the EV kit board. A Windows message appears when connecting the EV kit board to the PC for the first time. Each version of Windows has a slightly different message. If you see a Windows message stating ready to use, then proceed to the next step. Otherwise, open the USB_Driver_Help_200. PDF document in the Windows Start | Programs menu to verify that the USB driver was installed successfully. 5) Start the EV kit software by opening its icon in the Start | Programs menu. The EV kit software main window appears, as shown in Figure 1. The GUI indicates if the USB hardware is connected in the lower left status bar. 4   6) The VDUT supply should be set to 3.3V and can optionally be measured with a DMM on TP127. Adjustment to the VDUT supply can be made through resistor R100. 7) Connect the RF SMA connector to a spectrum analyzer to see the power level and modulation spectrum. Set the analyzer to a center frequency of 315MHz and the frequency span to 2MHz. 8) The IC operates in ASK mode by default. Set the IC’s carrier frequency to 315MHz by typing the frequency in MHz in the Center Frequency edit box. Then press Enter. 9) Set the PA output power level to 0x1E by selecting the value in the PA Setting drop-down list. 10) Click on the ENABLE (0x10) checkbox and verify that the value changes to 1. Verify that the lockdet light is also green. 11) Click on the DATAIN (0x11) checkbox. 12) The spectrum analyzer should display an unmodulated carrier at 315MHz. The power level depends on the value entered in Step 9. The maximum setting of 0x1E should produce a transmitted power level of approximately +15dBm (30mW to 35mW), with a 3.3V supply voltage. 13) To test FSK, uncheck the DATAIN (0x11) and ENABLE (0x10) checkboxes. 14) Click on the mode checkbox and verify that FSK is shown in the Conf0 (0x01) group box. In the FSK group box, the center frequency should be set to 315MHz. In the Frequency Deviation edit box, type in 50 and press enter. That produces a peak-topeak value that rounds to the frequency resolution of the synthesizer. Inside the FSK group box, the high and low frequencies are shown next to the fhi and flo labels. 15) Click on the ENABLE (0x10) checkbox. Verify that the DATAIN (0x11) checkbox is not checked. The spectrum analyzer should display an unmodulated carrier at the logic 0 (Space) frequency, which is approximately equal to the flo value. This frequency may be off by up to a few tens of kilohertz depending on the crystal frequency tolerance. 16) Toggle the DATAIN (0x11) checkbox and observe the frequency shift on the spectrum analyzer. The logic 1 (Mark) frequency should be near the fhi value.

Maxim Integrated   7 MAX7060 Evaluation Kit Evaluates: MAX7060 Layout Issues A properly designed PCB is essential for any RF/microwave circuit. Keep high-frequency input and output lines as short as possible to minimize losses and radiation. At high frequencies, trace lengths that are on the order of λ/10 or longer can act as antennas. Both parasitic inductance and capacitance are influential on circuit layouts and are best avoided by using short trace lengths. Generally, a 10 mil wide PCB trace, 0.0625in above a ground plane, with FR4 dielectric has approximately 19nH/in of inductance and approximately 1pF/in of capacitance. In the matching network, where the inductor is on the order of 22nH and a capacitor is on the order of 10pF, the proximity of the circuit to the IC has a strong influence on the effective component values. To reduce the parasitic inductance, use a solid ground or power plane below the signal traces. Also, use lowinductance connections to ground on all GND pins, and place decoupling capacitors close to all VDD connections. Do not share GND vias on decoupling capacitors; give each capacitor its own via. Detailed Description of Software The main window of the MAX7060 EV kit is shown in Figure 1. The EV kit uses Windows XP-, Windows Vista-, and Windows 7-compatible software to provide a simple GUI to demonstrate the MAX7060. The EV kit GUI Main Control 8   tab allows the IC to be set up easily without having to focus on programming the registers. The register values can be viewed in the Registers tab. This allows easy prototyping with the GUI with different configuration settings. Main Control Tab The Main Control tab highlights the features for setting the transmitter and GPO configuration. The transmitter frequency has a specified range through the GUI. The transmit frequency range is 301.5MHz to 450.5MHz, with a 16MHz crystal. The frequency can be changed to any value through the Registers tab, but only to the allowable values through the Main Control tab. The transmit frequency is the Center Frequency in the ASK group box. For FSK, the center frequency defines the midpoint between the Space frequency (flo) and the Mark frequency (fhi). The low and high frequencies are defined by the frequency deviation around the Center Frequency. The maximum PA power setting is selectable. Timing and power steps are also available for ASK digital shaping. The DATAIN and ENABLE functions can be set through software (checkbox) or hardware (button). The bit level and hardware logic are internally ORed. GPO Configuration The IOConf1 (0x05) group box shows the different signal output options that GPO1 and GPO2 have. The IOConf0 (0x04) group box gives the status of different internal signals, as shown in Table 4. These show up in the Status register as you change the value of TestMUX.

This allows complete configuration of the IC by writing to a single register. Manual Tab The IC can operate in a fixed hardware-only mode that requires no SPI controller. The Manual tab (Figure 2) allows the hardware settings to be controlled through software. Instead of jumpers to set the high and low logic levels, the on-board microcontroller sets the levels dependent on the settings chosen within this tab. The fixed hardware mode can also be manually controlled through JU1 and JU2. JU1 and JU2 need to be installed and shunts on JU111 (pins 3–30) need to be removed. Jumper positions can be toggled for different output settings. Registers Tab The Registers tab (Figure 3) displays each register’s individual bit logic-level status. A data bit in bold indicates a logic-high, while a data bit not bolded indicates a logic-low. Clicking on the individual data bit toggles the bit and performs a write and read command. The new value is shown in the edit boxes at the far right. Full register values can be written to the registers alternatively by 10   typing a hex value in the edit box and pressing the Enter key on the keyboard. Log Tab The Log tab can be used to verify that a command was executed. Next to the Log Page table is an edit box that shows what was last written to the Log Page. It is not necessary to switch to the Log Page to verify if a command was sent. Useful Tips The EV kit contains a simple GUI for demonstrating the IC. Some actions do multiple writes and reads in the background. To ensure that the software works correctly, follow these tips: • Make sure jumpers are installed in the default configuration. • When the program is started, verify that Hardware: Connected is displayed in the lower left status bar and MAX7060 Detected is displayed in the lower right status bar. • When unplugging the USB cable, wait approximately 5s before plugging it back in. This lets the supply voltage drop below the reset threshold. • After plugging the USB cable from the PC to the EV kit, wait approximately 5s before running the EV kit Maxim Integrated MAX7060 Evaluation Kit Evaluates: MAX7060 Figure 2.

Detailed Description of Hardware The MAX7060 EV kit provides a proven layout for the MAX7060. The IC can be operated with a 5V supply or a 3V supply. For hardware-only mode, populate jumpers JU1 and JU2 for the manual-mode settings. On-board test points are included to monitor various signals (Table 5). Power Amplifier Matching Network The matching network in the EV kit is a broadband network optimized for the low end of the operating frequency range. The best combination of power and efficiency is found between 300MHz and 330MHz. At the high end of the band (430MHz to 450MHz), the power is 2dB to 3dB lower compared to the low end of the band. This drop in power is the result of the harmonic-filter (C55-L2-C56) cutoff frequency being set to reject the second harmonic of the lower frequencies. Other matching-network component values can be used to move the optimum frequency range. Manual-Mode Operation Power Supply The IC can operate from a 2.1V to 3.6V or 4.5V to 5.5V supply. The EV kit has several options to power from the USB for both settings. The user can also externally supply a voltage to the control side. The 1-2 position on J100 allows the VDUT to be powered from a battery. Battery holders (not populated) are required. 3V Supply from USB To power from the USB supply with a 2.1V to 3.6V range, change the shunt on J100 to the 7-8 position on the control side. The shunt is in the 7-8 position by default. That position makes VDUT equal to VADJ. The user can monitor VADJ with a voltmeter and change the potentiometer resistance (R100) to adjust the voltage between 2.1V and 3.6V. On the DUT side, JU8 needs to be closed. 5V Supply from USB To power from the 5V USB supply, change the shunt on J100 to the 3-4 position on the control side. That position makes VDUT equal to 5V. JU8 needs to be open to operate in this state. The AVDD pin becomes an LDO output with a 5V input at HVIN, and generates the V3V supply net for the other supplies. See Tables 6, 7, and 8 for manual-mode settings. Table 5. DUT-Side Signal Test Points NAME GPO1 DESCRIPTION General-Purpose Output 1. In SPI mode, this test point can monitor internal status signals. In manual mode, this test point monitors the synthesizer lock-detect (lockdet) signal. LSHDN Low-Power Shutdown Current-Select Digital Input. Disables SPI when high. Must be driven low for normal operation in 3V mode. Functional only in 3V mode. Connect to GND in 5V mode. GPO2_MOD (SPI Mode/Manual Mode) Digital Signal. Acts as an SPI data output (SDO) when CS_DEV is low. ASK (0)/ FSK (1) modulation select input in manual mode. CS _DEV SDI_PWR1 SCLK_PWR0 ENABLE (SPI Mode/Manual Mode) Serial Peripheral Interface (SPI) Active-Low Chip-Select Signal. (SPI Mode/Manual Mode) SPI Data Signal in SPI Mode. Power-control MSB input in manual mode. (SPI Mode/Manual Mode) SPI Clock Signal in SPI Mode. Power-control LSB input in manual mode. Enable signal. All internal circuits (except the PA in ASK mode) are enabled on the rising edge of ENABLE. DIN Transmit Data Digital Signal. SDO See the GPO2_MOD description.

Then apply the external voltage between the VEXT and GND-_ test points. The jumper setting on JU8 is dependent on the input-supply voltage. If the input-supply voltage is between 2.1V and 3.6V, the jumper should be installed. If the input supply is between 4.5V and 5.5V, the jumper should be left open. need to be removed there, too. For example, to apply an external signal to DIN, first uncheck the DATAIN (0x11) checkbox. Then remove the jumper from pins 31-32 of JU111 and apply the DIN signal to the DIN test point. A complex pattern can be sent using the transmitter in this fashion. The enable works similarly. Make sure the voltage range of the external signals is limited to DVDD before applying the signals. Current Measurements for Individual Supplies The IC has various supply inputs that can all be monitored independently. These supplies are on the DUT side and powered by the V3V and V5V supply nets coming from the control side. All supplies are connected together by default. For supply current measurements for a specific supply, change the jumper associated with the supply and connect V3V or V5V through an ammeter to the corresponding test point. Remove the shunts from the SPI jumpers and apply the signals to the SPI test points. The SPI jumpers are located on JU111 (Table 2). See Table 9 for descriptions. The external SPI signals need to be limited to the DVDD supply voltage. J101 can be used for observing SPI signals on the control side (Table 10). Applying External Signals To apply an external signal to the enable (ENABLE) and Tx data (DIN) test points, the respective jumper on JU111 must first be removed and the signal applied to the signal test point. If JU1 is installed, the respective jumpers External SPI External Frequency Input For applications where an external frequency is desired over the crystal frequency, it is possible to apply an external frequency through the XTAL SMA connector. Remove the crystal and install resistor R12 (use 0I). The IC GUI default crystal frequency is 16MHz. Table 9.
