MAX3930/MAX3931/MAX3932
The MAX3930/MAX3931/MAX3932 are designed for
direct modulation of laser diodes at data rates up to
10.7Gbps. They provide adjustable laser bias and
modulation currents and are implemented using
Maxim’s second-generation in-house SiGe process.
The MAX3930 accepts differential CML clock and data
input signals and includes 50Ω on-chip termination
resistors. It delivers a 1mA to 100mA laser bias current
and a 20mA to 100mA modulation current with a typical
(20% to 80%) 25ps rise time. An input data retiming
latch can be used to reject input pattern-dependent jitter
if a clock signal is available.
The MAX3931/MAX3932 have an alternate pad out with
respect to the MAX3930. The MAX3931 includes the
series damping resistor R
D
on chip.
The MAX3930/MAX3931/MAX3932 also include an
adjustable pulse-width control circuit to minimize laser
pulse-width distortion.
