Quick Start
The MAX3514/MAX3516/MAX3517 EV kits are fully
assembled and factory tested. Follow the instructions in
the Connections and Setup section. Note: The output
circuit includes a minimum-loss pad that is used to
bring the load impedance up to 75Ω. This must be
accounted for in all measurements (see Output Circuit
section).
Note: The input transformer is supplied to allow differential input drive from a single-ended source. A transformer is not required in the application.
Test Equipment Required
• DC supply capable of delivering 5.5V and 200mA of
continuous current
• HP 8648 or equivalent signal source capable of generating 40dBmV up to 200MHz
• HP 8561E or equivalent spectrum analyzer with a
minimum 200MHz frequency range
• Digital multimeter (DMM) to monitor VCC and ICC, if
desired
• Lowpass filters to attenuate harmonic output of signal sources, if harmonic measurements are desired
• Network analyzer, such as the HP 8753D (may be
used to measure gain and harmonic levels if configured with this option; contact test equipment manufacturer)

pins labeled +5V and GND on the circuit board.
Connect a 50Ω signal source to INPUT (preset the
signal source for -13dBm (+34dBmV across a 50Ω
load)), and terminate OUTPUT with a spectrum analyzer or network analyzer having a 50Ω input impedance. If using a signal source with a source impedance other than 50Ω, or if a different input impedance is required, be sure to replace resistor R1 with
the appropriate value resistor.
2) Connect a 25-pin male-to-male cable between the
parallel (printer) port of the PC and the 25-pin
female connector on the EV kit board.
3) See Table 1 for board jumper settings.
4) Turn on the power supply. Turn on the PC and the
test equipment.
5) Run the software program.
Detailed Description
• IBM PC or compatible with Windows 95/98 installed
Using the Software
• Male-to-male 25-pin parallel cable, straight through
The MAX3514/MAX3516/MAX3517 use a serial data
interface (SDI) to set gain. Some means of communicating with the SDI is required to use the MAX3514/
MAX3516/MAX3517 EV kits. A microprocessor, pattern
generator, or PC can be used for this function.
Software is included in these EV kits to facilitate the use
of a PC.
• 0 to 5V pulse generator (transient measurement)
• Low-noise amplifier with 40dB gain from 5MHz to
100MHz (noise measurement)
• Oscilloscope with 200MHz bandwidth

The disks included with the MAX3514/MAX3516/
MAX3517 EV kits contain four files each. Table 2 lists
these files and their appropriate usage. If your PC has
Windows 95/98 installed, run MAX3514.EXE. The software can also be found on the Maxim website.
Gain Adjustment
The valid gain code ranges from 0 to 127 (decimal).
The nominal change in gain is 0.5dB per gain code.
Gain codes are set exclusively by programming the
SDI. Refer to the MAX3514/MAX3516/MAX3517 data
sheet for details.
High Power and Low Noise
High-power (HP) mode and low-noise (LN) mode may
only be controlled via the PC interface. Manual control
of the jumpers for the EV kits’ boards is not possible.
For DOCSIS applications, HP mode should be used for
output levels above 42dBmV. This corresponds to gain
code 87. LN mode should be used below this output
level. This corresponds to gain code 115. A transition
from HP mode, gain code 87, to LN mode, gain code
117, will result in a -1dB step.
Shutdown and Transmit Enable
Jumpers JU1 through JU4 determine how the shutdown
and transmit-enable features are controlled. Pin 2 of
JU2 and pin 2 of JU4 are connected directly to the
device. If an external source (such as a modulator chip
or microprocessor) is used to control these features,
make the connections to pin 2 of JU2 and pin 2 of JU4.
Pads are provided on the board (R18 and R19, respectively) for placement of termination resistors, if needed.
If manual control of shutdown and transmit enable is
desired, shunt pins 2 and 3 of jumper JU1 and pins 2
and 3 of jumper JU3. This will allow SHDN and TXEN to
be controlled by JU2 and JU4, respectively. JU2 and
JU4 are used to place either VCC or ground at SHDN or
TXEN. Pin 3 of JU2 and pin 3 of JU4 are ground, and
pin 1 is VCC.
To control the SHDN and TXEN features using the software, shunt pin 1 and pin 2 of JU1 and JU3.
Manual Control of Serial Data Interface
If using a source other than a PC to drive the serial data
interface of the MAX3514/MAX3516/MAX3517 EV kits
(such as a digital pattern generator or microprocessor),
remove the shunts on jumpers JU5, JU6, and JU7.
Access to the serial data interface is available through
these jumpers. Termination pads are provided (R2, R3,
R4). Solder an appropriate resistor to these pads, if
desired. Refer to the MAX3514/MAX3516/MAX3517
data sheet for a description of the serial data interface.

To control the SDI using the software, shunt pin 1 and
pin 2 of JU5, JU6, and JU7.
Input Circuit
The input circuits of the MAX3514/MAX3516/MAX3517
EV kits are configured with a 1:1 transformer (T1) and a
49.9Ω input resistor. This allows the input to be driven
with single-ended 50Ω test equipment. The transformer
(T1) is used to generate a differential signal, as rated
performance is specified with a differential input drive
(typically from a differential lowpass filter).
If the MAX3514/MAX3516/MAX3517 are to be driven
single ended, the input transformer (T1) must be
removed and the undriven input connected to ground
through a 0.1µF blocking capacitor.
Output Circuit
The MAX3514/MAX3516/MAX3517 have differential outputs. This architecture aids in suppressing secondorder distortion (harmonics). To convert to a singleended output, a 2:1 voltage ratio transformer (T2) is
used. Since most test equipment is supplied with a 50Ω
termination impedance, a minimum-loss pad is provided on the output of the transformer to increase the load
impedance to a nominal 75Ω. This places the proper
load on the device, but will also reduce the measured
output voltage level by 7.5dB. It is essential to consider
this when making any measurements with the EV kit;
7.5dB must be added to all measurements of voltage
gain and output voltage level (including noise) to arrive
at the correct value for a 75Ω system.
Use 75Ω test equipment, if available, and take the following steps:
1) Remove the 50Ω output SMA connector and replace
it with a 75Ω connector.
2) Remove R5 and replace it with a 0Ω resistor or some
other type of shunt.
3) Remove R21.
4) Be sure to use a 75Ω cable.
Analysis
Harmonic Distortion
A filter will be needed to reject the harmonics generated
by the signal source. For this example, a lowpass filter
with approximately a 25MHz to 35MHz cutoff frequency
will be required. This filter will need to reject at least
20dB of signal at 40MHz. Set the 50Ω signal source for
20MHz and -13dBm. Adjust the amplitude to account for
the insertion loss in the filter. Verify with the spectrum
analyzer that the second and third harmonics generated
by the source are suppressed by at least 70dBc.
_______________________________________________________________________________________
MAX3514/MAX3516/MAX3517 Evaluation Kits
Connect a spectrum analyzer to OUTPUT. Set the center frequency for 40MHz and the span for 50MHz or
more. Adjust the reference level so that the fundamental (20MHz tone) is within 10dB to 20dB of the reference level. If the fundamental is less than 10dB below
the reference level, the harmonic distortion of the spectrum analyzer may prevent accurate measurement of
the distortion.
Set the gain code to 125, D7 = 1 (approximately 27dB
of gain). Measure the level of the fundamental, second,
and third harmonics on the spectrum analyzer. These
readings have units of dBm. To convert from dBm to
dBmV in a 50Ω system, use the following equation:
X (dBmV) = Y(dBm) + 47dB (50Ω system)
Add 7.5dB to this value to account for the attenuation of
the minimum-loss pad, in dBmV, for a 75Ω load. The
gain can now be calculated in dB, and the harmonic
distortion can be calculated in dBc.
Switching Transients
To measure the transmit-enable and transmit-disable
transients, the TXEN pin will be driven from an external
source. No input signal is applied, and the output is
viewed on an oscilloscope.
Connect OUTPUT to the oscilloscope’s 50Ω input. Set
the scope’s time base to 5µs/div and the vertical scale
to 5mV/div.
Set the pulse generator as follows:
• Amplitude: 5V
• Duty cycle: 50%
• Rise/fall-time: 100ns
• Pulse width: 25µs
• Offset: 2.5V
Output Noise
To measure output noise, a spectrum analyzer is used.
A postamplifier with less than 10dB noise figure and
greater than 40dB gain within the band of interest is
needed.
With the power supply off, place a 50Ω termination on
the input of the EV kit.
Turn on the powers supply to the MAX3514/MAX3516/
MAX3517 EV kits. Using the software, set the device to
transmit mode with a gain code of 119, D7 = 1 (approximately 24dB of gain, MAX3514). Connect the output of
the postamplifier to the spectrum analyzer and the
input to OUTPUT on the EV kit. Set the spectrum analyzer as follows:
• Center frequency: 35MHz
• Span: 60MHz
• Reference: -50dBm
• Scale: 10dB/div
• IF bandwidth: 1kHz
Power up the postamplifier.
If the spectrum analyzer being used has a noise marker
function, enable it. The output noise can now be read
directly from the spectrum analyzer. Move this marker
to 42MHz. Read the value of the noise density from the
spectrum analyzer. This noise value is a combination of
the output noise of the MAX3514/MAX3516/MAX3517,
the gain of the postamplifier, and the noise figure of the
postamplifier. With the specified noise figure of 10dB,
the noise contribution of the postamplifier may be
ignored. The minimum-loss pad reduces the actual
measured value by 7.5dB. Use the following equation
to arrive at the MAX3514/MAX3516/MAX3517s’ output
noise in a 160kHz bandwidth:
VNOISE = PNOISE + 47dB + 7.5dB + 10 ✕ log
(160,000) - GAMP
where:
Take care not to drive the MAX3514/MAX3516/
MAX3517 TXEN pin below 0 or above +5V. Turn on the
power supply. Remove the shunt from jumper JU3
(TXEN), and connect the output of the pulse generator
to pin 2 of this jumper. Trigger the oscilloscope from
the pulse generator using a convenient method.
Set the gain code to 125, D7 = 1.
A rising- and falling-edge transient should appear on
the scope’s CRT. The amplitude of this transient should
be less than 40mVp-p. Multiply the value of the measured transient by 2.37 to account for the presence of
the minimum-loss pad. The gain may now be changed
to show the output transient’s dependence on gain.
VNOISE = MAX3514/MAX3516/MAX3517 output
noise in dBmV measured in a 160kHz bandwidth
PNOISE = Noise density in dBm/Hz read from the
spectrum analyzer
GAMP = Gain of the postamplifier in dB
If the spectrum analyzer being used does not have a
noise marker function, corrections must be made to
account for the IF bandwidth used to make the measurement. Consult the user’s manual for your spectrum
analyzer for details. Once the correction is made, the
value read from the spectrum analyzer can be converted to a noise density (dBm/Hz), and the above formula
can be used.

Layout Considerations
The MAX3514/MAX3516/MAX3517 evaluation board
can serve as a guide for your board layout. Particular
attention should be paid to thermal design and to the
output network. The MAX3514/MAX3516/MAX3517
package exposed paddle (EP) conducts heat out of the
part and also provides a low-impedance electrical connection. The EP must be attached to the PC board
ground plane with a low thermal and electrical impedance contact. Ideally, this would be provided by soldering the backside package contact directly to a top
metal ground plane on the PC board. Alternatively, the
EP could be connected to a ground plane using an
array of plated vias directly below EP.

The output circuit that connects OUT+ and OUT- (pins
15 and 16) to the output transformer (T2) should be as
symmetrical as possible to reduce second-order distortion. In addition, the capacitance of this path should be
kept low to minimize gain rolloff at high frequencies.
