MAX9209/MAX9244 Evaluation Kit

General Description

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

21-bit deserializer with programmable spread spectrum

and DC balance. The MAX9209 serializes 21 bits of

LVCMOS/LVTTL parallel input data to three LVDS out-

puts. The MAX9244 deserializes the three LVDS input

data from the MAX9209 and transforms it back to 21-bit

LVCMOS/LVTTL parallel data.

The MAX9209/MAX9244 EV kit circuits are implement-

ed on a single PCB and come with a MAX9209EUM+

and a MAX9244EUM+ installed.

MAX9209/MAX9244 Evaluation Kit

Evaluates: MAX9209/MAX9244

Detailed Description of Hardware

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.

Output Signals

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).

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.

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.

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.

MAX9209/MAX9244 Evaluation Kit

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.

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).

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.

Evaluates: MAX9209/MAX9244

Spread-Spectrum Frequency

The MAX9244 can set the frequency spread to ±4%,

±2%, 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.
