The MAX105 EV kit is a fully assembled and tested sur-
face-mount board. Follow the steps below for board
operation. Do not turn on power supplies or enable
function generators until all connections are
completed.
1) Connect a signal generator with low phase-jitter to
2) For differential operation, connect a ±380mV
3) Phase-lock both the VINI and/or VINQ signal gener-
4) Connect a logic analyzer, such as the HP16500 with

DC power supplies:
Generator with low phase-noise for clock input
(e.g., HP8662A, HP8663A, or equivalent)
Two signal generators for analog signal inputs (e.g.,
HP8662A, HP8663A, or equivalent)
Logic analyzer or data-acquisition system (e.g.,
HP16500C series, HP16517A 1.25Gbps state
module for single-ended evaluation.
User-selected analog bandpass filters (e.g., TTE
Elliptical Bandpass Filter, or equivalent)

(Figure 1). For a single-ended clock input (Figure
2), connect a 500mV (354mV

and terminate the unused CLK- input with a 50Ω
termination resistor to AGND.

test signal to connector A of the balun. Terminate
connector B of the balun with a 50Ω terminator.
Attach connector C of the balun to the analog input
VINI+ (VINQ+). Attach connector D of the balun to
the analog input VINI- (Figure 1). For single-ended
operation, apply the test signal to either VINI+
(VINQ+) or VINI- (VINQ-) and terminate the unused
input with a 50Ω resistor to AGND (Figure 2). For
best results, use a narrow bandpass filter designed
for the frequency of interest to reduce the harmonic
distortion of the signal generator.

The MAX105 EV kit evaluates the performance of the
MAX105 dual channel, 6-bit ADC at a maximum clock
frequency of 800MHz (400MHz for MAX107). The
MAX105 ADC can process differential or single-ended
analog and clock inputs. The user may apply baluns to
generate differential signals from a single-ended ana-
log signal to the EV kit.
The EV kit’s PC board incorporates a four-layer board
design to optimize the performance of the MAX105 in a
50Ω environment. Separate analog and digital ground
planes minimize noise coupling between analog and
digital signals. The EV kit requires a +5.0V power sup-
ply applied to the analog power plane, and a +3.3V
power supply applied to the digital power plane.
Access to the outputs is provided through the two-pin
headers (Table 1) all around the edge of the board. A
silkscreen on the PC board’s top layer indicates refer-
ence designations.
