EVALUATION BOARD

Figure 51 shows the schematic of the device’s RoHS-compliant

evaluation board. This board was designed using Rogers 4350

material to minimize losses at high frequencies. FR4 material

would also be adequate but with the slightly higher trace loss

of this material.

Whereas the on-board USB interface circuitry of the evaluation

board is powered directly from the PC, the main section of the

evaluation board requires a separate 5 V power supply.

The evaluation board is designed to operate using the internal

VCO (default configuration) of the device. Additional

configuration options for the evaluation board are described

in Table 11.

The serial port of the ADRF6704 can be programmed from a

PC’s USB port (a USB cable is provided with the evaluation

board). The on-board USB interface circuitry can if desired be

bypassed by removing the 0 Ω resistors, R15, R17, and R18 (see

Figure 51) and driving the ADRF6704 serial interface through

the P3 4-pin header (P3 must be first installed, Samtec TSW-

104-08-G-S).

EVALUATION BOARD CONTROL SOFTWARE

USB-based programming software is available to download

from the ADRF6704 product page at www.analog.com

(Evaluation Board Software Rev 6.1.0). To install the software,

download and extract the zip file. Then run the following

installation file: ADRF6X0X_6p1p0_customer_installer.exe.

To operate correctly under Windows XP, Version 3.5 of

Microsoft .NET must be installed. To run the software on a

Windows 7 PC, XP emulation mode must be used (using

Virtual PC).

Figure 50. Control Software Opening Menu

Figure 50 shows the opening window of the software where the

user selects the device being programmed. Figure 54 shows a

screen shot of the control software’s main controls with the

default settings displayed. The text box in the bottom left corner

provides an immediate indication of whether the software is

successfully communicating with the evaluation board. If the

evaluation board is connected to the PC via the USB cable

provided and the software is successfully communicating with

the on-board USB circuitry, this text box shows the following

message: ADRF6X0X eval board connected.
