General Description
Features
♦ 21-Bit Parallel LVCMOS/LVTTL Interface
The MAX9209/MAX9244 evaluation kit (EV kit) provides
a proven design to evaluate the MAX9209 21-bit pro-
grammable DC-balanced serializer and the MAX9244

MAX9209/MAX9244 Evaluation Kit
Output Signals
Detailed Description of Hardware
The MAX9244 outputs 21-bit parallel data at
LVCMOS/LVTTL levels on 40-pin headers H5 and H6.
To sample the 21-bit pattern, connect a logic analyzer
or data-acquisition system to H5 and H6. See Tables 6
and 7 for the output bit locations on the 40-pin headers
(H5 and H6).
The MAX9209/MAX9244 EV kit provides a proven
design to evaluate the MAX9209 21-bit programmable
DC-balanced serializer and the MAX9244 21-bit deseri-
alizer with programmable spread spectrum and DC
balance. The MAX9209 serializes 21 bits of LVCMOS/
LVTTL parallel input data to three LVDS outputs. The
MAX9244 deserializes the three LVDS input data from
the MAX9209 and transforms it back to 21-bit LVC-
MOS/LVTTL parallel data.
DC-Balance and Non-DC-Balance Modes
The MAX9209 operates at a parallel clock frequency of
8MHz to 34MHz in DC-balance mode by moving the
shunt of JU4 to the 1-2 position. The MAX9244 oper-
ates at a parallel clock frequency of 16MHz to 34MHz
in DC-balance mode by moving the shunt of JU9 to the
2-3 position.
Input Signals
The MAX9209 accepts 21-bit parallel data at LVC-
MOS/LVTTL. The 21-bit pattern is supplied to the EV kit
by connecting a data generator to the three 20-pin
headers (H1, H2, and H3), or by connecting selected
H1, H2, and H3 pins to high/low LVCMOS/LVTTL
states. See Tables 2, 3, and 4 for input bit locations for
H1, H2, and H3.
The MAX9209 operates at a parallel clock frequency of
10MHz to 40MHz in non-DC-balance mode by moving
the shunt of JU4 to the 2-3 position. The MAX9244
operates at a parallel clock frequency of 10MHz to
40MHz in non-DC-balance mode by moving the shunt
of JU9 to the 1-2 position.

MAX9209/MAX9244 Evaluation Kit
Evluates:0/MAX924
The MAX9209 features an on-chip PRBS generator that
can be utilized to generate a pseudo-random bit
stream to evaluate the quality and performance by
comparing the output of the serializer (prior to the
link/cable) with the input of the deserializer (after the
link/cable).
Power-Down
The power-down mode in the MAX9209 and MAX9244
puts the outputs in high impedance, stops the PLL, and
reduces supply current to 50µA or less by moving the
shunts of JU2 and JU11 to the 2-3 position. When JU2
and JU11 are in the 1-2 position, the LVDS outputs of
the MAX9209 are not driven until the PLL locks and the
LVDS outputs of the MAX9244 are driven low until the
PLL locks.
To activate this feature, the MAX9209 must first enter
power-down mode by moving the shunt of JU2 to the 2-
3 position. Activate the internal PRBS mode by moving
the shunt of JU3 to the 2-3 position.
Spread-Spectrum Frequency
The MAX9244 can set the frequency spread to 4ꢀ,
2ꢀ, or no spread by moving JU10 to the appropriate
shunt position (Table 1).
Power Supplies
The MAX9209 is powered by connecting PLL1_VCC,
LVDS1_VCC, and VCC1 to a DC power supply at 3V to
3.6V. The MAX9209 can be configured to reduce wiring
to the supply and ground pads by moving the shunts of
JU16 and JU17 to the 1-2 position. The MAX9244 is
powered by applying 3.3V to 3.6V to the PLL2_VCC,
LVDS2_VCC, VCC2, and VCC0 pads. The MAX9244
can be configured to reduce wiring to the supply and
ground pads by moving the shunts of JU18, JU19, and
JU20 to the 1-2 position.
Pseudo-Random Bit Sequence
(PRBS) Mode
The MAX9209/MAX9244 EV kit offers the user an inter-
nal test mode to quickly verify full functionality and veri-
fication of the quality of the SerDes link. This mode is
called pseudo-random bit sequence, or PRBS mode.
