MAX3941
Detailed Description
The MAX3941 EAM driver consists of two main parts: a
high-speed modulation driver and an EAM-biasing
block. The clock and data inputs to the driver are com-
patible with PECL and CML logic levels. The modula-
tion and bias currents are output through the OUT pin.
The modulation output stage is composed of a high-
speed differential pair and a programmable current
source with a maximum modulation current of 120mA.
The rise and fall times are typically 23ps. The modulation
current is designed to produce an EAM voltage up to
3.0VP-P when driving a 50
module. The 3.0VP-P results
from 120mAP-P through the parallel combination of the
50
EAM load and the internal 50 back termination.
Polarity Switch
The MAX3941 includes a polarity switch. When the
PLRT pin is high or left floating, the output maintains the
polarity of the input data. When the PLRT pin is low, the
output is inverted relative to the input data.
Clock/Data Input Logic Levels
The MAX3941 is directly compatible with ground-refer-
ence CML. Either DC- or AC-coupling can be used for
CML referenced to ground. For all other logic types,
AC-coupling should be used.
Optional Data Input Latch
To reject pattern-dependent jitter in the input data, a syn-
chronous differential clock signal should be connected to
the CLK+ and CLK- inputs, and the RTEN control input
should be connected to VEE.
