com 19-2730; Rev 0; 1/03 10Gbps EAM Driver with Integrated Bias Network General Description The MAX3940 is designed to drive an electro-absorption modulator (EAM) at data rates up to 10.
7Gbps.
It incorporates the functions of a biasing circuit and a modulation circuit, with integrated control op amps externally programmed by DC voltages.
The integrated bias circuit provides a programmable biasing current up to 50mA.
This bias current reflects a bias voltage of up to 1.
25V on an external 50Ω load.
The bias and modulation circuits are internally connected on chip, eliminating the need for an external bias inductor.
A high-bandwidth, fully differential signal path is internally implemented to minimize jitter accumulation.
When a clock signal is available, the integrated data-retiming function can be selected to reject input-signal jitter.
The MAX3940 receives differential CML signals (ground referenced) with on-chip line terminations of 50Ω.
The output has a 50Ω resistor ...
