Detailed Description and
Applications Information
The MAX3805 adaptive equalizer is designed to oper-
ate with 9.95Gbps to 10.7Gbps PRBS nonreturn-to-zero
(NRZ) data at the receive end of a transmission line,
typically differential 6-mil FR-4 PC board. It adaptively
corrects intersymbol interference caused by frequency-
dependent path loss. It can also be used with coaxial
cable links and with transmission lines that include well-
engineered connectors, as long as the total path loss is
relatively smooth and does not exceed 20dB at 5GHz.
The signal path for the MAX3805 consists of a CML
input stage, two amplifiers feeding a pair of variable
attenuators controlled by feedback, and a limiting
amplifier with a CML output stage. An enable input, EN,
is used to control the output stage. A signal-detect out-
put, SD, indicates when input signal to the transmission
line is above 220mVP-P or below 200mVP-P, typically.
See the
Functional Diagram.
CML Input and Output Buffers
The MAX3805 CML input and output buffers are inter-
nally terminated with 50
Ω to VCC1 and VCC2, respec-
tively. The input and output circuitry have separate
voltage connections to control noise coupling and pro-
vide DC-coupling to +1.8V, +2.5V, or +3.3V CML. If
desired, the CML inputs and outputs can be AC-cou-
pled. See Figure 1 for the output structure.
The low-frequency cutoff of the input-stage offset-can-
cellation circuit is nominally 21kHz.
For single-ended operation (typically coaxial cable
links), the input must be AC-coupled; connect the
unused input to VCC1 using a series combination of an
AC-coupling capacitor and a 50
Ω resistor, as shown in
Figure 2. Note that the MAX3805 is specified for differ-
ential operation, and the performance may be reduced
in single-ended operation.
