GigOptix adds low-power, small-form-factor surface-mount 4x32Gbps linear quad-channel modulator driver for coherent applications

GigOptix Inc of San Jose, CA, USA (a fabless supplier of analog semiconductor and optical communications components for fiber-optic and wireless networks) has announced sample availability of its newest linear quad-channel Mach-Zehnder Modulator (MZM) driver for low-power 100Gbps DP-QPSK coherent long-haul transmitter applications. Full volume-production shipments are expected to begin in third-quarter 2014.

GigOptix says that the release of the GX62474 low-power consumption linear driver in a small surface- mount technology (SMT) package further strengthens its position in the telecom driver market. The SMT package is optimized for minimum crosstalk and maximum isolation between each of the four channels. The GX62474 is designed to integrate seamlessly into customer modules by providing internal RF input and output DC blocking capacitors. RF supply chokes are provided with the small-form-factor SMT package for best performance and a high level of integration to minimize overall cost. Channel performance optimization has been enabled via independent gain and peak detector controls. Each of the 4x32Gbps broadband amplifiers is capable of driving up to 6Vpp of linear output voltage, suitable for multi-level modulation applications.

The GX62474 has demonstrated power dissipation lower than 2.0W per channel at 5Vpp linear output in a small-form-factor SMT package. The quad 32Gbps linear driver was designed for very low total harmonic distortion, large dynamic range, and very low group delay variation to address linear coherent long-haul telecom systems. It also has a 27GHz typical 3dB bandwidth, very small data skew between channels, and small gain response variation across power supply and temperature. “The GX62474 is an outstanding modulator driver which enables multi-level modulation applications required in today’s market and has been sampled already by number of our existing and new telecom key customers,” says Marco Cipriani, senior director of engineering.
