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. The modulator driver is characterized for operation from –40°C to 100°C case temperature and is available in a small footprint 3-mm × 3-mm 16-pin RoHS compliant QFN package.
