The ONET1151M is a high-speed, 3.3-V modulator driver designed to modulate a differentially driven Mach
Zehnder Modulator at data rates from 1 Gbps up to 11.35 Gbps.
The output amplitude can be controlled with an externally applied voltage. A 2-wire serial interface allows digital
control of the equalizer, output pre-emphasis, eye crossing point, rise and fall times, and the amplitude,
eliminating the need for external components. Output waveform control, in the form of pre-emphasis, cross-point
adjustment and rise and fall time adjustment are available to improve the optical eye mask margin.
An optional input equalizer with 10 dB of boost at 5 GHz can be used for equalization of up to 300-mm (12 in.) of
microstrip or stripline transmission line on FR4 printed circuit boards. …
