_______________Ge n e ra l De s c rip t io n

____________________________Fe a t u re s

The MAX3681 evaluation kit (EV kit) simplifies evalua-

tion of the MAX3681 622Mbps, SDH/SONET 1:4 deseri-

alizer. The EV kit requires only a single +3.3V supply

and includes all the external components necessary to

interface with 3.3V PECL and LVDS logic. The board

can be connected directly to the output of a clock-and-

data-recovery circuit (such as the MAX3675) and to the

input of an LVDS device (such as an overhead termina-

tion circuit). A signal generator or stimulus system can

b e us e d with a n os c illos c op e , to e va lua te the

MAX3681’s basic functionality.

♦ Single +3.3V Supply

♦ Inputs and Outputs Terminated for Interfacing

with 3.3V PECL and LVDS Logic

♦ Fully Assembled and Tested

The MAX3681 EV kit s imp lifie s e va lua tion of the

MAX3681. The EV kit operates from a single +3.3V sup-

ply and includes all the external components neces-

sary to interface with 3.3V PECL and LVDS logic.

Each PECL input (SCLK+, SCLK-, SD+, SD-) is termi-

All LVDS outputs (PCLK+, PCLK-, PD_+, PD_-) are dif-

ferentially terminated with 100Ω resistors between com-

plementary outputs. Each output can directly drive an

LVDS input or a high-impedance input oscilloscope

(see the section Connecting LVDS Outputs to 50Ω

Input Oscilloscopes). When driving an LVDS input that

already includes 100Ω differential termination, remove

the termination resistor corresponding to the appropri-

ate LVDS output.

0.1µF ceramic capacitors

33µF, 6.3V tantalum capacitor

2.2µF ceramic capacitor

The synchronization inputs (SYNC+, SYNC-) are inter-

nally terminated LVDS inputs with 100Ω differential

input resistance. Ensure that LVDS devices driving

these inputs are not redundantly terminated.

All signal inputs and outputs use coupled 50Ω trans-

mission lines. All input signal lines are of equal length

to minimize propagation-delay skew. Likewise, all out-

put signal lines are of equal length.

MAX3681 data sheet

To monitor an LVDS signal on a 50Ω input oscilloscope,

remove the differential load resistor between the com-

plementary outputs and AC couple each output to an

oscilloscope input. For example, to observe the PD0

signal on a 50Ω input instrument, remove resistor R12

from the EV board and place a capacitor or DC block in

series with each output (PD0+ or PD0-) and the instru-

ment input. Do not connect MAX3681 outputs directly

to 50Ω inputs or terminations to ground. Choose a

coupling capacitor large enough in value to prevent pat-

tern-dependent distortion of the output signal.
