MAX3543 Evaluation Kit
Evaluates: MAX3543
_______________________________________________________________________________________ 3
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 operat-
ing 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 connec-
tors 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 jump-
ers 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 periodi-
cally 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.
