The MAX3935 is designed to drive an electro-absorption
modulator (EAM) at data rates up to 10.7Gbps. It
provides programmable output levels through externally
adjustable bias and modulation currents. This EAM
driver is fabricated with Maxim's in-house second-generation
SiGe process.
The MAX3935 accepts differential ECL or ground-referenced
CML clock and data-input signals. Inputs are
terminated with on-chip 50Ω resistors. An input-data
retiming latch can be used to reject input-pattern-dependent
jitter if a clock signal is available.
The driver can modulate EAM devices at amplitudes up
to 3.0VP-P when the device impedance is 50Ω. Typical
(20% to 80%) edge speeds are 34ps. The output has
an on-chip 75Ω resistor for back termination. The
MAX3935 allows for an EAM bias voltage up to 1.2V.
The MAX3935 also includes an adjustable pulse-width
control circuit to precompensate for asymmetrical EAM
characteristics.
