Quick Start
The MAX3543 EV kit is fully assembled and factory
tested. Follow the steps in the Connections and Setup
section for proper device evaluation.
Test Equipment Required
•
Power supply capable of supplying at least 300mA,
+3.3V
•
RF signal generator capable of delivering at least
0dBm of output power at the operating frequency
•
RF spectrum analyzer capable of covering the
operating frequency range of the device
•
50I SMA cables
•
User-supplied PC with Windows XP® or later operating system and an available USB port
•
USB cable with USB-A male connector on one end
and USB-B male connector on the other end
•
(Optional) Dual-output power supply capable of
supplying up to 3V at < 1mA (to apply gain-control
voltages directly).
•
(Optional) Ammeter to measure supply current
Connections and Setup
This section provides a step-by-step guide to testing
the basic functionality of the EV kit in DVB-T mode. For
user’s convenience, Figure 1 illustrates critical connectors on the INTF3000+ USB interface board and the EV
kit. Caution: Do not turn on DC power or RF signal
generator until all connections are completed.
1) Connect the provided 20-pin ribbon cable between
the INTF3000+ board (J1 labeled as INTF2400) and
the EV kit JP2 connector. Make sure that pin 1 of the
INTF3000+ board J1 connector is connected to pin
1 of the EV kit JP2 connector (see the red wire on the
20-pin ribbon cable in Figure 1).
2) Make sure that JU1 on the INTF3000+ board is in
the “VDEV” position. Verify that the J6 and J7 jumpers are not present.
3) Connect the USB cable between the PC’s USB
port and the INTF3000+ board. The red light on the
INTF3000+ board should light once briefly when the
board is connected to the PC. It also blinks periodically as the EV kit software communicates with the
board.
4) Verify that jumpers JP3 and JP5 are installed on the
EV kit.
5) With its output disabled, set the DC power supply
to +3.3V. Connect the power supply to the VCC
(through an ammeter if desired) and GND terminals
on the EV kit. If available, set the current limit to
300mA.
6) With its output disabled, connect the output of the
RF signal generator to the SMA connector labeled
“RFIN” (J1) on the EV kit.
7) Connect the IFOUT_DTV output (J3) to a spectrum
analyzer.
8) Turn on the +3.3V power supply. The supply current
should read approximately 260mA. If an ammeter is
used, be sure to adjust the power supply to account
for any voltage drop across the ammeter.
9) Install the IC's control software provided by Maxim.

10) Maxim also provides a FactorySettings.ini file that
includes predefined MAX3543 register configurations for different TV standards (DVB-T, DVB-C, PAL,
SECAM). Manually copy the FactorySettings.ini file
into the directory where the IC software is installed.
The path should be “C:\Program Files\Max3543\” or
similar.
15) Go to the Synth tab and set the REF FREQ to match
the crystal frequency (in MHz) on the EV kit. Most of
the EV kits use 16MHz crystals.
11) Launch the IC control software.
17) Load the predefined factory settings to set the
MAX3543 registers to receive the desired TV
standard. For instance, to configure the device for
reception of DVB-T signals, choose the Factory
Settings → DVB-T menu item. Note that Maxim
provides predefined configurations for most of the
existing TV standards. If custom optimization is
desired, use these settings as a starting point.
12) Verify that the I²C write address setting in the EV
kit software (Options → I²C Write Address menu
item) matches the EV kit hardware configuration. By
default, the EV kit comes with no jumper installed
on the JP4 header. This corresponds to the address
setting of 0xC2.
13) Verify that the software shows “Board/USB-Online”
in a green box at the bottom of the window. If the
status is “OFFLINE-Click Here,” then verify all the
connections described above in steps 1 through 8.
14) Go to the Options → External IF Bandpass Filter
menu item and select the IF bandpass filter used at
the IFOUT1 output on the EV kit. Most of the EV kits
use a differential LC filter. It is important to select the
appropriate mode to ensure that the right IFOUT1
output driver (differential vs. single-ended) is used
to drive the bandpass filter.
USB (TO PC)
16) Set the IF FREQ to the desired value. Note that the
on-chip bandpass filter is centered at 36.15MHz,
so the IF FREQ should be set within ±0.2MHz of
36.15MHz.
Gain Measurement to the IFOUT_DTV
Port in DVB-T Mode
1) Connect the dual-output power-supply outputs
to the RFVGC and IFVGC terminals on the EV
kit. Adjust voltages at RFVGC and IFVGC to be
approximately +3V.
2) Load the predefined factory settings for DVB-T
mode by selecting the Factory Settings → DVB-T
menu item.
3) Enter the desired RF frequency (e.g., 666MHz) into
the RF FREQ text box in the RF Top tab.

RF Gain-Control Range (RFVGC)
To measure the gain-control range in the RF stage, follow
the steps below:
5) Set the RF signal generator to a 666MHz frequency
and a -90dBm power level. Enable the RF signal
generator’s output.
2) Set IFVGC to +3V.
6) Set the center frequency of the spectrum analyzer
to 36.15MHz and the span to 1MHz. Set the reference level to 0dBm. Increase the input power of the
signal generator until the output level reaches
-22dBm. This is the output level that corresponds
to approximately 1VP-P output across the IC's
DTVOUT+ and DTVOUT- pins. The voltage gain of
the receiver can be calculated by taking the difference in dB between the input and output power and
applying correction factors to compensate for the
50ω-to-75ω min loss pad at the input (R10 and R11),
T1 balun (4:1 impedance ratio), and R7 442ω series
resistor at the output.
Voltage gain can be calculated from:
AV = 3.96dB + 20 LOG(VOUT,RMS/VIN,RMS)
+ 6dB +19.86dB
or
AV = (POUT - PIN) + 29.82dB
where:
3.96dB is the voltage loss due to the input min
loss pad,
P (dBm) − 30
VIN,RMS = 50x10 IN
10
is the input RMS voltage calculated from the input
power PIN (i.e., power from the RF signal generator),
P
(dBm) − 30
VOUT,RMS = 50x10 OUT
10
is the output RMS voltage calculated from the
output power POUT (i.e., power at the spectrum
analyzer input),
6dB is the output transformer voltage ratio,
19.86dB (i.e., 20 LOG(492/50)) is the voltage loss
due to R7 series resistor.
The calculated voltage gain should be approximately 85dB.
1) Set RFVGC to +3V.
3) Adjust the RF input power to achieve -22dBm at the
IFOUT_DTV output. Record this as the reference
output level.
4) Set RFVGC to +0.5V and record the change in the
IFOUT_DTV output level in dB relative to -22dBm.
This change in output power is the gain-control
range of the RF stage.
5) The RF gain-control range should be approximately
53dB.
6) Note that it might be necessary to increase the input
power level with RFVGC = +0.5V in order to make
an accurate level measurement. If this is necessary,
calculate the RF gain-control range by first calculating the gain with RFVGC = +3V, then calculate the
gain with RFVGC = +0.5V and take the difference
between these two gain levels.
IFVGA Gain-Control Range (IFVGC)
To measure the gain-control range in the IFVGA stage,
follow the steps below:
1) Set RFVGC to +1V.
2) Set IFVGC to +3V.
3) Adjust the RF input power to achieve -40dBm at the
IFOUT_DTV output. Record this as the reference
output level.
4) Set IFVGC to +0.5V and record the change in the
IFOUT_DTV output level in dB relative to -40dBm.
This change in output power is the gain-control
range of the IFVGA stage.
5) The IFVGA gain-control range should be approximately 42dB.
6) Note that it might be necessary to increase the input
power level with IFVGC = +0.5V in order to make
an accurate level measurement. If this is necessary,
calculate the IFVGA gain control range by first calculating the gain with IFVGC = +3V, then calculate
the gain with IFVGC = +0.5V and take the difference
between these two gain levels.

Gain Measurement to the IFOUT_ATV
Port in PAL-B/G Mode
1) Connect the IFOUT_ATV output (J4) to a spectrum
analyzer.
2) Adjust the RFVGC voltage to approximately +3V.
3) Load the predefined factory settings for PAL-B/G
mode by selecting the Factory Settings → PAL/
SECAM B/G/D/K/I (IFOUT2 output) menu item.
4) Enter the desired RF frequency (e.g., 506MHz) into
the RF FREQ text box in the RF Top tab.
5) Set the RF signal generator to the desired RF frequency and a -60dBm power level. Enable the RF
signal generator’s output.
6) Set the center frequency of the spectrum analyzer to
36.15MHz and the span to 1MHz. Set the reference
level to 0dBm. Increase the input power of the signal generator until the output level reaches -28dBm.
This is the output level that corresponds to approximately 0.5VP-P output at the IC's IFOUT2 pin. The
voltage gain of the receiver can be calculated by
taking the difference in dB between the input and
output power and applying correction factors to
compensate for the 50ω-to-75ω min loss pad at the
input (R10 and R11), and R13 500ω series resistor
at the output.
Voltage gain can be calculated from:
AV = 3.96dB + 20 LOG(VOUT,RMS/VIN,RMS)
+ 20.83dB
or
AV = (POUT - PIN) + 24.8dB
where:
3.96dB is the voltage loss due to the input min
loss pad,
P (dBm) − 30
VIN,RMS = 50x10 IN
10
P
(dBm) − 30
VOUT,RMS = 50x10 OUT
10
is the output RMS voltage calculated from the
output power POUT (i.e., power at the spectrum
analyzer input),
20.83dB (i.e., 20 LOG(550/50)) is the voltage loss
due to R13 series resistor.
The calculated voltage gain should be approximately 44dB.
Connecting the MAX3543 to Digital and
Analog Demodulators
The EV kit includes additional input and output
connectors to allow for quick and easy evaluation of the
IC's performance with digital and analog demodulators.
The differential input of the digital (or digital + analog)
demodulator can be connected to the DTV 3-pin header
on the EV kit. The IFAGC output of the demodulator
should be connected to the IFVGC terminal on the EV kit.
The IC controls its RF gain autonomously, so the RFVGC
terminal on the EV kit should be left unconnected.
Older analog demodulators with single-ended input and
built-in IF gain-control stage can be connected using the
ATV 2-pin header on the EV kit. The RFVGC terminal on
the EV kit should be left unconnected.
The device also provides the buffered reference clock
output that can be used by demodulators. Use the
REFOUT 2-pin header to connect the clock output to the
demodulator reference clock inputs.
Layout Considerations
Contact Maxim to obtain the MAX3543's reference
design layout to use as a starting point for PCB designs.
Refer to the Layout Recommendations section in the
MAX3543 IC data sheet for more information.
