GigOptix launches 32G quad-channel linear modulator driver for coherent CFP and CFP2 modules in metro 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 launched the GX62476 linear quad-channel modulator driver for low-power coherent metro applications.
The firm says that the GX62476 extends its telecom driver market leadership position into metro applications with a quad-channel, 32Gbps solution offering what is claimed to be the lowest power dissipation of less than 1.1W/channel at a 5VPP swing using a 5V supply voltage and 0.75W/channel at a 3VPP swing using a 3.3V supply voltage.
The GX72476 linear driver is optimized for use with available low-drive-voltage lithium niobate and indium phosphide (InP) optical modulators, requiring single-ended drive to provide low power consumption with what is claimed to be the best linearity solution in a small-form-factor SMT package for coherent CFP and CFP2 modules.
The GX62476 was designed for very low total harmonic distortion, at both 5VPP and 3VPP, and very low group delay variation to address linear coherent metro applications. It also has a 27GHz typical 3dB bandwidth and provides for adjustable output voltage. The miniaturized SMT package is suitable for the high level of integration required by the CFP2 form factor and reduced power operation requirements.
The GX62476 is sampling now and will ship in full production volumes from second-quarter 2015.
