MAX19505–MAX19507/
MAX19515–MAX19517 Evaluation Kits
Connecting the DCEP to the EV Kit
The DCEP and the EV kit boards can be connected
using the specified on-board connectors. J5 on the EV
kit mates with J5 on the DCEP board. Alternatively, the
two boards can be connected with coaxial ribbon
cables (Samtec, part no. HQCD-060.00-STR-TBR-1).
Note that it is necessary to use either the on-board con-
nectors or cables to obtain a reliable electrical connec-
tion between the two boards.
Power Supplies
The MAX19505–MAX19507/MAX19515–MAX19517 EV
kits operate from a single 5V DC power supply (VIN)
and provide on-board regulation to power the analog,
digital, and clock-shaping circuit blocks. The analog
and clock (AVDD) are regulated to 1.8V through the
MAX8902A (U14), a pin-selectable linear regulator. The
digital output is regulated to 1.8V through the
MAX8902A (U15) as well. SW1 and SW2 are provided
to select the desired output of U14 and U15. See
Tables 1 and 2 for AVDD and OVDD supply options.
The MAX8511 (U13) regulates VIN to provide a 1.8V
DC to power the logic circuitry (VLOGIC). Jumpers JU9
and JU10 are provided to either disconnect or measure
current through AVDD and OVDD, respectively.

AVDD (SW1)
Clock Input
The data converter allows for either differential or sin-
gle-ended signals to drive the clock inputs. The
MAX19505–MAX19507/MAX19515–MAX19517 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 single-
ended analog input and generates a differential analog
signal, which is then applied to the ADC’s input pins.
Configuring the EV Kits for
Single-Ended Clock Operation
To configure the MAX19505–MAX19507/MAX19515–
MAX19517 EV kits for single-ended clock operation, the
following modifications must be made to the clock circuit:
1) Cut the traces at locations R47, R48, and R49.
2) Install 0 ? resistors at locations R51 and R52.
3) Install a 49.9 ? ±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 ana-
log input signals. Insertion losses due to a series-con-

nected 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.

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-compati-
ble 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.
