Evaluation Kits
General Description
The
MAX19505–MAX19507/MAX19515–MAX19517
evaluation kits (EV kits) are fully assembled and tested
circuit boards that contain all the components necessary
to evaluate the performance of this family of 8-bit and
10-bit analog-to-digital converters (ADCs). The EV kits
also include Windows® 7/10-compatible software that
provides a simple graphical user interface (GUI) for
exercising the programmable features of the MAX19505/
MAX19507/MAX19515–MAX19517.
The MAX19505–MAX19507/MAX19515–MAX19517 EV
kits accept a single-ended analog input from an analog
signal source. The EV kits provide an on-board circuit that
transforms this analog single-ended signal into a differential
signal. The ADC digital output can be captured easily with
a basic logic analyzer. The EV kits can operate from a
single 3.6V nominal power supply and provide on-board
regulation for the analog, clock, digital, and logic circuitry.

www.maximintegrated.com
5) Verify that shunt is installed across jumper J8, and no
jumper is installed across J10 (OVDD = 1.8V).
6) Connect the clock generator output to the clock bandpass filter input.
7) Connect the output of the clock bandpass filter to the
CLK SMA connector.
8) Connect the output of the analog signal generator to
the input of the signal bandpass filter. Keep the cable
connection between the signal generators, filters, and
EV kit board as short as possible for optimum dynamic performance.
9) Connect the output of the signal bandpass filter to the
VINA SMA connector. Note: It is recommended that a
3dB or 6dB attenuation pad be used to reduce reflections and distortion from the bandpass filter.
10) If using IO3200, apply power to the IO3232A by
connecting the USB cable from the computer’s typeA USB port to the IO3232A module’s mini-USB port.
11) Connect the MAX195xx J5 header pins to the logic
analyzer (See Connecting the IO3232A to the EV Kit
below, if applicable).
12) Connect the power supply to VSUPPLY. Connect the
ground terminal of this supply to the corresponding
GND pad.
13) Connect the USB cable from the computer’s type-A
USB port to the EV kit board’s Mini USB port.
14) Visit www.maximintegrated.com and search for
the device EV Kit to download the latest version of
the MAX195xx EV kit software and install it on your
computer by running the INSTALL.EXE program. The
program files are copied and icons are created in the
Windows Start menu.
15) Start the MAX195xx program by opening its icon in
the Start menu.
16) Turn on the 5V power supply.
17) Enable the signal generators.
18) Set the clock signal generator for an output amplitude
of 2VP-P or higher (recommended +16dBm to +19dBm
for optimum AC performance for input frequencies >
100MHz) and the frequency (fCLK) as appropriate.
19) Set the analog input signal generators for an output
amplitude of less than or equal to 2VP-P and to the
desired frequency.
20) Verify that the two signal generators are phase locked
to each other. Adjust the output power level of the
signal generators to overcome cable, bandpass filter,
and attenuation pad losses at the input.
21) Collect data using the logic analyzer.

Detailed Description of Hardware
The MAX19505–MAX19507/MAX19515–MAX19517
evaluation kits (EV kits) are fully assembled and tested
circuit boards that contain all the components necessary
to evaluate the performance of this family of 8-bit and
10-bit analog-to-digital converters (ADCs).
The ADCs accept differential input signals; however,
on-board transformers (T1–T4) convert a readily available single-ended source output to the required differential
signal. The input signals of the ADCs can be measured
using a differential oscilloscope probe at headers J2 and J3.
Output drivers (U11 and U12) buffer the output signals of
the data converter. The digital outputs of each EV kit are
accessible at header J5.
Each EV kit is designed as a four-layer PCB to optimize
the performance of this family of ADCs. Separate analog,
digital, clock, and buffer power planes minimize noise
coupling between analog and digital signals. The 100Ω
differential microstrip transmission lines are used for
analog and clock inputs. The 50Ω microstrip transmission
lines are used for all digital outputs. The trace lengths of
the 100Ω differential input lines are matched to within a
few thousandths of an inch to minimize layout-dependent
input-signal skew.
Using the IO3232A with the EV Kit
The Logic Analyzer Pattern Generator (IO3200) is one
of the many instrument options to evaluate the performance of this specific family of evaluation kits. While it is
simple enough to use, this method does require the user
to download the IO3200 software from the following link:

Evaluation Kits
Connecting the IO3232A to the EV Kit
The IO3232A can be connected to the MAX195xx boards
using the following pin ordering. It is not essential to
match the pins exactly as specified below, as they are a
recommended connection sequence.
Configuring the EV Kits for
Single-Ended Clock Operation
To configure the MAX195xx EV kits for single-ended clock
operation, the following modifications must be made to
the clock circuit:
1) Remove 0Ω resistors at locations R47, R48, and R49.
Power Supplies
The MAX195xx EV kits operate from a single DC power
supply (VSUPPLY) and provide on-board regulation
to power the analog, digital, and clock-shaping circuit
blocks. The nominal voltage input for the VSUPPLY is at
3.6V. The maximum voltage supported by the MAX195xx
EV kits is 5V, and the minimum voltages are represented
in Table 1 and Table 2 based on the user’s desired regulated voltage. The analog and clock (AVDD) are regulated
to a desired voltage (1.8V, 2.5V, 3.0V, or 3.3V) through the
MAX8902A (U14), a pin-selectable linear regulator. The
digital output and logic circuitry (OVDD and VLOGIC) are
both regulated to a desired voltage (1.8V, 2.5V, 3.0V, or
3.3V) through the MAX8902A (U15). J1, J8, J9, and J10
are provided to select the desired output of U14 and U15.
See Table 2 and Table 3 for AVDD and OVDD/VLOGIC
supply options. Jumpers JU9 and JU10 are provided to
either disconnect or measure current through AVDD and
OVDD, respectively.
2) Install 0Ω resistors at locations R51 and R52.
3) Install a 49.9Ω ±1% resistor at location R50.
In single-ended clock configuration, potentiometer R46
can be utilized to control the duty cycle of the clock input
signal. Measure the clock input at J4 and adjust R46 until
the desired duty cycle is achieved.
Input Signal
Although this family of ADCs accepts differential analog
input signals, the EV kits only require single-ended analog
input signals. Insertion losses due to a series-connected
filter and the interconnecting cables decrease the amount
of power seen at the EV kit input. Account for these losses
when setting the signal generator amplitude. On-board
transformers (T1–T4) convert the single-ended analog input
signals and generate the recommended differential analog
signals at the ADCs’ differential input pins. The input circuit
supports input frequencies from 1MHz to 400MHz.
Clock Input
The data converter allows for either differential or singleended signals to drive the clock inputs. The MAX195xx
EV kits support both methods.
In single-ended operation, the clock signal is applied to
the ADC through a buffer (U10). In differential mode, an
on-board transformer converts a user-supplied singleended analog input and generates a differential analog
signal, which is then applied to the ADC’s input pins.

Output Signal
The MAX19505, MAX19506, and MAX19507 feature
two 8-bit, parallel, CMOS-compatible digital outputs that
transmit the converted analog input signals. The higher
resolution MAX19515, MAX19516, and MAX19517 feature two 10-bit, parallel, CMOS-compatible digital outputs
that transmit the converted analog input signals. Each set
of 8-bit or 10-bit digital outputs also includes a clock bit
(DCLKA/B) and overrange bit (DORA/B) to accommodate
data synchronization and error detection. See the Output
Bit Locations section for more details on how to configure
these 8-bit and 10-bit converter outputs.
Output Bit Locations
Two drivers (U11 and U12) buffer the digital outputs
of the individual ADCs. These drivers are able to drive
large capacitive loads, which may be present at the
logic analyzer connection. The outputs of the buffers are
connected to J5.
Serial Port Enable (SPEN)
The SPEN pin selects the means of programming
the internal registers of the MAX19505–MAX19507/
MAX19515–MAX19517 ADCs. SPEN is set high or low
based on the settings of jumper JU7, shown in Table 4.
When a shunt on JU7 is installed, the 3-wire serial port is
disabled and the part can be programmed through jumpers
JU1, JU2, and JU3 in parallel mode. When JU7 is left
open, SPEN is pulled to GND through R44. Refer to the
Table 4. Jumper JU7 Functions
respective IC data sheet for more information on SPEN
and parallel programming. Note that when the serial port
is enabled, jumpers JU1, JU2, and JU3 must be set to
pins 1-3 for proper operation.
Shutdown (SHDN)
The MAX19505–MAX19507/MAX19515–MAX19517
ADCs can also be placed in a low-power shutdown
mode through jumper JU6. This pin has different effects
depending on the state of SPEN. When in SPI programming mode, SHDN can select between two powermanagement states. When in parallel programming mode,
SHDN can enable/disable the IC.
When SPI programming is enabled (SPEN = 0), the SHDN
pin is a toggle switch between two power-management
states, shown in Figure 2 under the Power Management
group box of the software interface. When a shunt is
installed on JU6, SHDN is connected to AVDD and the
user can select the appropriate settings for CHA Active,
CHB Active, Standby, and A+B Adder mode under the
label **Use when SHDN = 1 (IC pin 7)**. When no shunt
is installed on JU6, SHDN is connected to GND through
R43 and the user can select the appropriate settings for
CHA Active, CHB Active, Standby, and A+B Adder
mode under the label **Use when SHDN = 0 (IC pin 7)**.
When parallel programming mode is enabled (SPEN = 1),
the SHDN pin enables/disables the IC according to the
settings in Table 5.

Parallel Programming
Limited feature selection is available as an alternative to
full programmability through the serial port. If the serial
port is disabled by setting the SPEN pin high, the serial
port pins (CS, SCLK, SDIN) become feature selection
pins (OUTSEL, DIV, FORMAT) that require an analog
control network.
Jumpers JU1, JU2, JU3, and JU7 control the
feature selection when the serial port is disabled (parallel
programming is enabled). See Table 6 for functionality.
