MAX3802UGK
3.2Gbps Quad Adaptive Cable Equalizer with Cable Driver
General DescriptionThe MAX3802 has four independent adaptive cable
equalizers and cable drivers on a single chip. It is
designed for coaxial and twin-axial cable point-to-point
scrambled-data communication applications. The dri-
ver features differential current-mode logic (CML)
inputs and outputs. The equalizer includes differential
CML data inputs and outputs and a TTL loss-of-signal
(LOS) output.
The adaptive cable equalizer can equalize differential
or single-ended signals at data rates up to 3.2Gbps. It
automatically adjusts to attenuation caused by skin-
effect losses of 30dB at 1.6GHz. The equalizer effec-
tively extends the usable length of copper cable in
high-frequency interconnect applications.

ABSOLUTE MAXIMUM RATINGS
DC ELECTRICAL CHARACTERISTICSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

AC ELECTRICAL CHARACTERISTICS(VCC= 3.14V to 3.46V, TA= 0°C to +85°C. Typical values are at VCC= 3.3V and TA= +25°C, unless otherwise noted.)
Note 2:Input voltage within specification limits, 50Ωto VCCat each output.
Note 3:Minimum cable input for LOS_to deassert high.
Note 4:100kΩload to ground. The minimum input signal level that turns off the LOS_alarm depends on the data rate and cable length.
Note 5:AC electrical characteristics are guaranteed by design and characterization.
Note 6:VDIN_= 400mVP-Pto 1100mVP-P(differential), 10kΩ≤RMOD_≤20kΩ, 3.2Gbps 213-1 PRBS plus 100 consecutive ones and
100 consecutive zeros.
Note 7:Includes random jitter and deterministic jitter for BER of 10-12.
Note 8:Differential cable input voltage = 400mVP-P, 3.2Gbps 213-1 PRBS plus 100 consecutive ones and 100 consecutive zeros.
Note 9:Isolation test: three channels driven with identical 3.2Gbps PRBS with maximum input signal to each equalizer and maxi-
mum input signal on driver. The measured channel meets the residual and random jitter specifications with an uncorrelated
3.2Gbps PRBS data at minimum input signal level on equalizer and maximum signal level on driver.
Note 10: Equalizer time constant measured from data on to closed-loop operation.
