BVA303/305/518

Introduction

The BVA303/305/518 is a gain amplifier with enhanced 6-bit RF Digital Step Attenuator(DVGA) designed for use in 3G/4G wireless infrastructure and other high performance RF applications. An inte-grated digital control interface supports both serial and parallel programming of the attenuation, in-cluding the capability to program an initial attenuation state at power-up. Covering a 31.5 dB attenua-tion range in 0.5 dB steps, it maintains high linearity and low power consumption from 30~40MHz through 4 GHz. BVA303/305/518 also features an external negative supply option, and is offered in a 24-lead 4x4 mm QFN package. The BVA303/305/518 Evaluation Kit (EVK) includes the application software and hardware required to control and evaluate the functionality of the DVGA using a PC running the Windows operating system to control the USB interface board

Application support

MCM BVA303/305/518 Evaluation Board Assembly

Overview

The Evaluation Board is assembled with a BVA303/305/518 DVGA, SP2T mechanical switch (P/S), Paral-lel Programming switches (D1~D6,LE), several headers, and SMA connectors. The P/S switch is used for Parallel or Serial mode selection. The D1~D6,LE switches are used for setting the control bits in Direct Parallel programming mode.

DVGA Interface Board V1.0 Hardware Operation (BVA303/305 Evaluation Board Realease)

1. Verify that all DC power supplies are turned off before proceeding

2. Connect the jumper on JP1, JP2

3. Set jumpers of PUP1 (J7) and PUP2 (J8) to be “HIGH” at upper position and “LOW” at down position

4. Position the P/S switch to Parallel or Serial mode (Left:Parallel & Latched Parallel, Right:Serial)

5. Set the D1~D6 and LE mechanical programming switches on board to support Direct Parallel, Latched Parallel, or Serial mode

a. Serial or Latched Parallel mode(using GUI application software on PC)

- Place D1~D6 and LE at the middle position to support Latched Parallel and Serial modes with

GUI application software and proper position of P/S switch

b. In Direct Parallel mode(Using SP3T switch on Interface board without PC)

- D1~D6 can be set to “HIGH” or “LOW” to manually program the attenuation state while LE is

connected to “HIGH” without using the Mini USB Interface and GUI application software

Table 1. SP3T Switch Descriptions for parallel mode

6. Provide external power supply to the J4 connector (refer to the Operating Ranges table in the datasheet for the voltage range)

a. VDD is the positive power supply with 3.0V typical

b. VDD_DIG is the positive power supply for control signals with 1.8V typical, and it can be connected to VDD with jumper

on JP1 to simplify the test set-up

c. VSS is the external negative power supply with –3.3V typical. To simplify the test set-up, it can also be shorted to GND with

jumper on JP2 to enable using the internal negative voltage generator

Remark : In order to evaluate the DVGA of the evaluation board on parallel or serial mode, You should

connect the USB cable to a PC. And then to supply an External power VDD or VDD_DIG to the evalua-

tion board.

USB Driver Installation The latest USB interface board drivers are available via Microsoft Windows update. Internet connectivity is required to download the drivers. Connect the USB interface board to the PC and select the Windows Update option to obtain and install the drivers. If the USB board drivers are not installed, it will not be possible to run the program correctly.

A USB interface board (Figure 5) is included in the

Evaluation Kit. This software is available directly from FTDI’s website at http://www.ftdichip.com/Drivers/VCP.htm Recommend : For Windows XP, USB Serial Converter & Port Driver recommend 2.10.00(x86:32-bit, x64:64bit) WHQL Certified file.

Driver

FTDI Driver Installation For Windows 8 and 7, drivers will be installed auto-matically when your computer is connected to the Internet. Alternatively, you may install the drivers from the file web site download (http://www.ftdichip.com/Drivers/VCP.htm) Connect the USB Serial converter to an available USB port, and the “Found New Hardware Wizard” will guide you through the installation process. When prompted to connect to Windows Updates to search for drivers, select “No, not at this time”, and follow the instructions for installing from the file downloaded Once the drivers are successfully installed, the USB Serial converter will show up in the Windows Device Manager: Under “Ports (COM & LPT)”: labeled as “USB Serial Port (COMx)”, and under “Universal Serial Bus controllers”: labeled as “USB Serial Converter” (Figure 10-b). IMPORTANT NOTES: If it’s the first time you install the driver for

CommFront’s USB to Serial device, you will need to install the driver twice. One is for “USB Serial Converter”, and the other one is for “USB Serial Port”.

DO NOT close the 2nd “Found New Hardware Wiz-ard” window while installing the driver.

Upon completion of driver installations, remember to check the Windows Device Manager to make sure that the drivers are installed properly (Figure 10-a). If the drivers are not installed correctly, there will be a yellow exclamation icon displayed under the “Ports (COM & LPT)” or “USB Serial Bus controllers”, right-click on the yellow exclamation icon and select “Update driver”. Then search for the driver
