LMH2832EVM-50 Evaluation Module
The LMH2832EVM-50 evaluation module (EVM) is used to evaluate the dual LMH2832, digitally-controlled
variable gain amplifier (DVGA) in a 40-pin VQFN package. The EVM is used to easily demonstrate the
functionality and performance of LMH2832 across all the gain settings in a 50-Ωinput environment. The
EVM is ready to connect to power supplies, signal source, USB, and test instruments through the use of
onboard connectors. By default, the LMH2832EVM powers up to the 10-dB gain setting with the board
supporting only single-supply operation. A USB connector on the EVM facilitates programming of the
DVGA gain registers using an FTDI USB-to-SPI bus translator chip.

4 Setup Procedure
This section describes the hardware setup procedure and the installation of the software to program the
LMH2832 registers.
4.1 Connect EVM to a 5-V Bench Power Supply
1. Before making connections from the bench power supply to the evaluation board supply pin connector,
set the bench power supply to 5 V, and switch the bench power supply OFF.
2. While the supplies are turned OFF, connect the evaluation board power supply pins (V+ and GND) to
the bench power supply of 5 V and GND, as shown in Figure 2, using a low-noise bench power supply.
3. Turn ON the bench supplies after the power supply connections have been made. The LMH2832
evaluation board should read an approximate DC current of 204 mA for 5-V single supply with both the
LMH2832 channels enabled. Input and output pins should be biased to the mid-supplies as specified in
the LMH2832 data sheet (SBOS709) for proper operation.
4.2 Connect EVM to the External Signal Source at the Input
1. The LMH2832EVM-50 evaluation board provides the customer flexibility in testing at different input
frequencies using on-board input and output baluns as shown in Figure 2.
2. It is recommended to use 6-dB attenuator pads at the input while connecting a 50-Ωsignal source to
the LMH2832EVM-50 evaluation board SMA inputs.
3. TI recommends using a low pass or band pass filter in-between the signal source and the evaluation
board while measuring the harmonic distortion or inter-modulation distortion products.
4.3 Connect EVM to the External Test Equipment at the Output
1. The LMH2832EVM-50 evaluation board has SMA connectors at the output and can be directly
connected to 50-Ωtest equipment as shown in Figure 2.
2. While connecting the evaluation board output to an oscilloscope, make sure the oscilloscope is set in a
50-Ωtermination for the correct voltage reading on the oscilloscope.
4.4 PD (Power Down) Input
1. The LMH2832EVM has jumpers (J6 and J8) that allow the individual channels of the amplifier to be
manually disabled. The LMH2832 EVM consumes less than 9 mA of supply current with both the
LMH2832 channels disabled.
2. The PDA and PDB SMA input connector facilitates driving the LMH2832 PDA and PDB pins with a
high-speed signal source. Note that the PD SMA input connector should to be terminated on-board
with 50 Ωto GND (R11 and R12) so as to provide high-frequency termination for signals from a 50-Ω
pulse generator.

4.5 Connect EVM to the PC and LMH2832 EVM GUI Installation
The LMH2832 EVM GUI is used to control the LMH2832 EVM. It must be used to properly configure the
LMH2832 device.
1. Download the LMH2832 EVM GUI (SLOC338) from the TI website.
2. Extract the files from the zip file.
3. Run setup.exe and follow the installation prompts.
4. Connect the LMH2832EVM to the PC using a mini-USB cable.
5. Open the LMH2832 EVM GUI by going to Start Menu →All Programs →Texas Instruments →
LMH2832 EVM GUI.
6. Verify that the green USB Status indicator is lit in the top right corner of the GUI. If it is not lit, click the
Reconnect USB button and check the USB Status indicator again. If it is still not lit, then verify the EVM
is connected to the computer through the included mini-USB cable.
7. Follow the instructions in Section 5:Amplifier Device Register Configuration to correctly use the GUI to
program the LMH2832 device registers.
8. The DVGA register address and configuration values are found in the LMH2832 device data sheet
(SBOS709).
5 Amplifier Device Register Configuration
The LMH2832 channels are programmable via the serial programming interface (SPI) bus accessible
through the FTDI USB-to-SPI converter chip located on the EVM. A GUI is provided to write instructions
on the bus and program the registers of the LMH2832.
The LMH2832 individual channel gain can be controlled from –9 dB to 30 dB in 1-dB steps using register
address 5h and 7h for channels A and B, respectively. The amplifier is programmed to the maximum gain
(30 dB) when a value 0h is written to the gain control registers 5h and 7h, whereas a value 27h written to
the gain control registers programs the device to the minimum gain (–9 dB) setting. Table 2 shows the
default LMH2832 SPI register map on power up. For more information about the registers in the
LMH2832, see the LMH2832 data sheet (SBOS709).

6 Evaluation Troubleshooting
Issue Troubleshoot
Problem reading or writing the
LMH2832 device using the LMH2832
EVM GUI:
Verify that the green USB Status indicator is lit in the top
right corner of the GUI. If it is not lit, click the Reconnect USB
button and check the USB Status indicator again. If it is still
not lit, then verify the EVM is connected to the computer
through the included mini-USB cable.
Check to see whether the connectors to power supply pins of
the LMH2832 EVM are connected properly and turned ON.
The nominal supply current for the LMH2832EVM for 5-V
supply is approx 204-mA with both the channels enabled.
Low supply current: See if one of the device channels is disabled by the PDA or
PDB jumper. Also, check to see if the power supply is set to
the right voltage.
No supply current: See if the power supply cable connections are connected
and the power switch of the source is turned ON.
High supply current: The reverse supply protection diodes may be conducting.
Turn off the power switch and make sure the positive supply
is connected to the proper pin. Turn the power back on to
see if the correct supply current is recorded.
