The MxL9207 from MaxLinear is a quad-channel Lithium Niobate (LiNbO3) Mach-Zehnder (MZ) modulator driver for next-generation 100Gbps optical DWDM coherent systems. It supports DP-QPSK/BPSK coherent design for ultra-long-haul optical networking applications. The modulator driver has per-channel data rate of 32Gbaud with low jitter and low power dissipation performance. The device has output crossing-point and output amplitude control. It also has an integrated bias-tee to maintain optimal power dissipation. The device is available in a 19 x 13 mm SMT package.
