factors. See the Typical Operating Characteristics Cable
Driver Output Voltage vs. RMOD for typical values.
Cable Integrity Monitor
The CIM_ output voltage is directly proportional to the
output current of the loop amplifier (which controls the
current-steering network; see Detailed Description).
This is an analog voltage output that indicates the
amount of equalization being applied.
The amount of equalization (and thus the CIM_ output
level) is affected by cable type, cable length, signal
bandwidth, etc. See the Typical Operating Char-
acteristics CIM Voltage vs. Cable Length for typical val-
ues under specific conditions.
Loss-of-Signal (
LOS_) Output
Loss of signal is indicated by the LOS_ output. A low
level on LOS_ indicates that the equalizer input power
has dropped below a threshold. When there is suffi-
cient input voltage to the channel (typically greater than
250mV), LOS_ is high. The LOS_ output is suitable for
indicating problems with the transmission link caused
by, for example, a broken cable or a defective driver.
Data Spectrum for Equalizer
The MAX3802 equalizer design requires the data
stream be scrambled or coded to provide a rich fre-
quency spectrum for the adaptation algorithm.
Scrambled patterns or coded patterns with scrambled
content, such as 64b/66b or SONET PRBS, are ideal.
Some coded patterns, such as 8b/10b, lack low-fre-
quency energy and can be nonoptimal, requiring the
user to characterize the specific application. In the
absence of an input signal (nonstandard application),
amplified noise may appear at the output due to the
large gain of the device.
Single-Ended Operation
For single-ended operation of the cable driver or equal-
izer, connect the unused input to ground through a
series combination of a capacitor (of equal value to
other AC-coupling capacitors) and a 50 resistor. Note
that the MAX3802 is specified for differential operation.
Layout Considerations
The MAX3802’s performance can be significantly
affected by circuit board layout and design. Use good
high-frequency design techniques, including minimiz-
ing ground inductance and using controlled-imped-
ance transmission lines for the high-frequency data
signals. Power-supply decoupling capacitors should be
placed as close as possible to VCC.
Exposed-Pad Package
The EP on the 68-pin QFN provides a very low thermal
resistance path for heat removal from the IC. The pad is
the electrical ground on the MAX3802 and must be sol-
dered to the circuit board ground for proper thermal and
electrical performance. Refer to Maxim Application Note
HFAN-08.1, Thermal Considerations for QFN and Other
Exposed-Pad Packages (available at www.maxim-
ic.com) for additional application information.
