Detailed Description
General Theory of Operation
The MAX3784/MAX3784A adaptive equalizers extend
the reach of transmission lines in high-frequency back-
plane interconnect applications. They can be used for
4.25Gbps Fibre Channel, 4x 1.25Gbps Ethernet (5Gbps)
and other NRZ, 8b10b or short (
≤ 20 bits) CID data
types. Internally, the MAX3784/MAX3784A are com-
prised of an equalizer control loop and limiting output
driver. The equalizer block reduces intersymbol interfer-
ence (ISI), compensating for frequency-dependent
media-induced loss. The equalization control detects the
spectral contents of the input signal and provides a con-
trol voltage to the equalizer core, adapting it to different
media. The equalizer operation is optimized for short-run,
DC-balanced transmission codes.
Standby Mode
Standby saves power when the equalizer is not in use.
The EN logic input must be set high or open for normal
operation. Logic low at EN forces the equalizer into the
standby state.
CML Input and Output Buffers
The input and output buffers are implemented using cur-
rent-mode logic (CML). Equivalent circuits are shown in
Figures 3 and 4. For details on interfacing with CML,
refer to Maxim Application Note HFAN-01.0:
Introduction
to LVDS, PECL, and CML. The common-mode voltage
of the input and output is above +2.5V. AC-coupling
capacitors are required when interfacing this part with
devices terminated in voltages such as +1.8V. Values of
0.10F or greater are recommended.
