EVALUATION BOARD HARDWARE

OVERVIEW

The EVAL-ADF4158EB1Z is supplied with a cable for connecting to the USB port of a PC. The silk screen for the evaluation board is shown in Figure 2. The board schematic is shown in Figure 7, Figure 8, and Figure 9.
It is very important to note that the AV pins of the ADF4158 should never exceed the V ADF4158. This can cause damage to the device.
If the user wishes, external power supplies can be used. In this case, insert SMA connectors as shown on the silk screen (see Figure 2) and the digital picture (see Figure 1) of the evaluation board.

LOOP FILTER

The loop filter schematic is included in the board schematic in Figure 7, Figure 8, and Figure 9. The loop filter component placements are clarified in Figure 3.

LOCAL OSCILLATOR COMPONENTS

The 10 MHz TCXO provides the reference frequency. The on-chip R divider should be set to 1 so that the PFD frequency is also 10 MHz. The PLL is made up of the 10 MHz TCXO, the ADF4158, a passive loop filter (20 kHz bandwidth), and the VCO V940ME03 VCO from Z Communications. The output is available at RF
08972-002
The on-board loop filter has been designed for a charge pump current of 0.3125 mA. ADIsimPLL, a free download available at
www.analog.com/pll, can be used to design other loop filters.

EVALUATION BOARD SOFTWARE

The control software for EVAL-ADF4158EB1Z is on the CD that accompanies the board. To set up the software, use the following steps:
1. Click setup.exe.
2. The installation wizard appears. Follow the on-screen
instructions.
3. The software is installed in a default directory called
C:/Program Files/Analog Devices/ADF4x5x. To run the software, click the .exe file. Ensure that Version 3.3 was downloaded (Help > About).
While starting the software, choose USB Port in the Communication Selection section of the device window. The EVAL-ADF4158EB1Z cannot be programmed by the parallel port. Once the board is detected, a blue USB Detected box appears in the bottom left corner of the main window (see Figure 5).

MAIN WINDOW

In the main window, basic PLL settings can be chosen (see Figure 5). Most important are the parameters in both RF sections. Initially they are set to values that allow for correct operation of the EVAL-ADF4158EB1Z. The RF VCO output frequency should be within the range of the chosen VCO. The PFD frequency should be the value for which the loop filter was designed. REF reference signal. For VCO frequencies below 3 GHz, use a prescaler of 4/5 and for VCO frequencies above 3 GHz, use a prescaler of 8/9
In the RF section on the right side, program the charge pump current setting to the value for which the loop filter was designed. Charge pump polarity should usually be positive unless inverting active loop filter configuration is used. The CSR Disabled/CSR Enabled button offers cycle slip reduction (one of the fast-lock mechanisms). The RF Counter Reset Disabled/RF Counter Reset Enabled button brings PLL counters out/in of the reset state. The CP 3 State Off/CP 3 State On button brings the charge pump out/in of tristate.
In the top left corner, the RF Powerdown Disabled/RF
Powerdow n Enabled button powers up/down the part. The Program Fast Lock button is used for configuring switched-R
fast lock. The Fastlock Disabled/Fastlock Enabled button is used for deactivating/activating switched-R fastlock. The LDP = 3 button is used for setting lock detect precision. Muxout chooses the signal that is connected to the output of the multiplexer.
In the bottom right corner, the FSK Setup button opens the window for setting FSK modulation parameters, the button opens the window for activating PSK modulation, the Ramp Setup button programs ramps, and the Frequency Hop button enables jumping between frequencies.

RAMP SETUP WINDOW

The Ramp Setup window chooses various types of ramps with their specific options (see Figure 6). Ramp selection allows for selecting a continuous triangular, sawtooth ramp, single sawtooth burst ramp, or single ramp burst. Basic settings that configure a ramp are located in the Deviation Frequency/No of Steps and Timer Setting sections. Deviation Frequency determines the frequency step of a ramp, and Dev. Offset sets frequency resolu- tion. Dev. Freq. Res. specifies is the smallest frequency deviation that can be used. Use a small value of frequency resolution for precise but short ramps and big value of frequency resolution for long, but less precise ramps. The No. of steps text box deter­mines the number of steps that comprise a ramp. The Timer text boxes are used for setting the duration of a single step.
After choosing the aforementioned settings, activate the ramp by clicking the Start Ramp button in the bottom right corner of the software window.
The software also allows for evaluating other ADF4158 features: frequency readback, dual ramp rates mode, ramp mode with FSK signal on ramp, delayed start, and delay between ramps.
In the Dual Ramp Rates Mode section, program both Ramp1 and Ramp2. This is done by selecting On and Ramp1 first. Once Ramp1 is selected, settings for this particular ramp should be updated in the Deviation Frequency/No of Steps and Timer Setting sections. Then select Ramp2; settings for this ramp should also be updated in the Deviation Frequency/ No of Steps and Timer Setting sections.
In the Ramp Mode with FSK Signal on Ramp section, set the deviation frequency of the FSK signal superimposed on a ramp. Ramp settings are chosen in Deviation Frequency/No of Steps and Timer Setting sections.
The Delayed Start section chooses the delay of the ramp’s start. The first option (Delay = t selected for short delays (it also gives better resolution of time delay). The second option (Delay = t should be selected for long delays.
The Delay between Ramps section chooses the delay between ramps. The first option (Delay = t selected for short delays (it also gives better resolution of time delay). The second option (Delay = t should be selected for long delays. There is also a fast-lock option in this section, which can be used for reducing the overshoot in a sawtooth ramp.
