Detailed Description
General Theory of Operation
The MAX3804’s low-noise linear input stage includes
two amplifiers, one with flat-frequency response, and
one with response that compensates for the loss
characteristic of an FR-4 PC board transmission line.
A current-steering network allows the designer to
control the amount of equalization to match the path
loss for specific applications. This network consists of a
pair of variable attenuators feeding into a summing
node. Equalization is set by a 3-bit LVTTL-compatible
input (EQ3, EQ2, and EQ1). By employing fixed control
of the equalization level, the MAX3804 provides optimal
performance for a specific path loss. A high-speed
limiting amplifier follows the equalizer circuitry to shape
the output signal (see Figure 1).
CML Input and Output Buffers
The MAX3804 input and output CML buffers are termi-
nated with 50
to VCC1 and VCC2, respectively. The
equivalent circuit for the output is shown in Figure 2.
Separate supply voltage connections are provided for
the core (VCC), input (VCC1), and output (VCC2) circuit-
ry to control noise coupling, and to allow DC-coupling
to +1.8V, +2.5V, or +3.3V CML ICs. The CML inputs
and outputs can also be AC-coupled.
Use AC-coupling for single-ended cable applications.
The unused CML input must be connected through an
AC-coupling capacitor to a 50
termination.
The low-frequency cutoff of the input-stage offset-can-
cellation circuit is nominally 21kHz.
