Quick Start
Required Equipment
• MAX9247/MAX9248 EV kit (cable included)
• Two 3.3V DC power supplies
• Digital data generator (e.g., HP/Agilent 16522A)
• Two low-phase-noise clock generators (e.g., HP/
Agilent 8133A)
• Logic analyzer or data-acquisition system (e.g., HP/
Agilent 16500C)
• High-performance oscilloscope (e.g., HP/Agilent
DSO80304B; see the Pseudo-Random Bit Sequence
(PRBS) Mode section)
Procedure
The MAX9247/MAX9248 EV kit is fully assembled and
tested. Follow the steps below to verify board operation.
Caution: Do not turn on the power supplies or signal
sources until all connections are completed.
1) Verify that all jumpers (JU1–JU21) are in their default
positions, as shown in Table 1.
2) Connect the first 3.3V power supply across the
DVCC1 and GND1 pads of the EV kit.
3) Connect the second 3.3V power supply across the
DVCC2 and GND2 pads of the EV kit.
4) Connect the GND1 and GND2 pads together.
5) Connect the Rosenberger cable from the P1 to the P2
connector of the EV kit.
6) Connect the data generator to the H6–H9 connectors
and set to generate 27-bit parallel data at LVCMOS/
LVTTL levels. See Table 2 for input bit locations.
7) Connect the first clock generator to the P4 SMA con-
nector and set its output frequency between 2.5MHz
and 42MHz (see Table 3 for PCLK_IN location).
8) Connect the second clock generator to the P3 SMA
connector and set to within Q2% of the MAX9247 seri-
alizer PCLK_IN frequency (see Table 3 for REFCLK
location).
9) Connect the logic analyzer or data-acquisition system
to connectors H1 and H2, as shown in Table 4.
10) Turn on the power supplies.
11) Enable the clock generators.
12) Enable the data generator.
13) Enable the logic analyzer or data-acquisition system
and begin sampling data.
