Quad Channel 56 Gbaud Linear EML Driver

The MAOM-005411 is a high performance quad channel linear EML driver for 56Gbaud PAM4 applications with up to 100 Gbps payload on a single wavelength. The device can be driven with a differential input signal up to 1000 mVpp and has linear differential to single-ended voltage gain which is adjustable from 3 dB to 9 dB. The single-ended linear output voltage can be adjusted up to 1.8 Vpp with typical power dissipation of 0.3 W per channel and total harmonic distortion of less than 4 %. The part is packaged in a 7 mm x 7.2 mm surface mount package with integrated high frequency coils and coupling capacitors. It also incorporates peak detectors on each of the outputs for use in an APC loop.
